Description
Convipen (also styled ConviPen) is a blue, automatic, spring-driven reusable pen listed by Daro Pep for compatible 3 mL cartridges. It uses 1-unit settings up to 60 units and provides audible clicks during operation. This listing is for the bare pen only: no travel case, retail box, cartridge, needle, or liquid is included.
How the Convipen works
After an amount is selected, the spring-driven mechanism completes its operating stroke when the button is pressed. A remaining-volume stop helps prevent selecting an amount larger than the cartridge contents. Daro Pep classifies the Convipen as fully depleting when fewer than 2 units remain; that comparison label does not mean the cartridge reaches an absolute zero remainder.
Daro Pep lists the Munan sterilized and siliconized 3 mL cartridges as a compatible pairing that does not require an adapter in this pen. Fit can vary among other cartridges and needles described as 3 mL or pen-compatible, so confirm the exact combination rather than assuming universal compatibility.

Convipen compared with Gansulin
Convipen and the Gansulin Automatic Pen share several cataloged characteristics: automatic spring-driven operation, a compatible 3 mL cartridge format, and 1-unit settings up to 60 units. They are separate products and should not be described as identical. Convipen is blue and ships without a case; Gansulin is green and currently includes a travel case. See those differences alongside the rest of the catalog on the pen comparison page.
Convipen FAQ
Is Convipen an autoinjector?
Daro Pep describes it as an automatic, spring-driven reusable pen. “Automatic” refers to the spring-driven operating stroke after a setting is selected; it should not be confused with every product sold under the broader autoinjector label.
Which cartridges fit?
Daro Pep lists its Munan 3 mL cartridges as a compatible pairing. “3 mL” alone does not guarantee that every cartridge from every supplier has identical dimensions or operating tolerances.
Does Convipen require an adapter?
No adapter is listed as necessary with the Daro Pep Munan cartridge pairing. Avoid extending that statement to unverified cartridges.
Is there a verified Convipen manual?
Daro Pep does not currently identify a verified Convipen-branded PDF manual. A generic ServoPen template should not be presented as a Convipen manufacturer manual.
Source note
Incepta product information uses the ConviPen name. Package contents, compatibility statements, and the depletion classification above come from Daro Pep catalog records, not from that external page.

I bought several of these Convipens from Daro (I also have Gansulin pens). This pen is exactly the same as the Gansulin pen, I literally cut one of each of them apart to see- exactly the same!
Daro has the best prices on all pens, especially these and Novo pens.
If you want a autopen, this is it and Daro is the place to get it.

Received the pen quickly, securely shipped, and I love it. I will be ordering more.

I have bought 3 pens and this one is my favorite- the ‘trigger’ is the end of the pen (seems more natural to me?) and the ‘clicks’ as it administers the dosage is a satisfying feedback.

Of all the pens, I have tried this one is my favorite. I like the clicking the feedback. The mechanism to inject is at the end of the pen instead of on the barrel. I also like that it takes the three mil generic cartridges without needing any adapter. It just works.

its a nice pen, but i found that the dose it delivers heavily depends on whether the cartridge is full or empty – this may have to do with using it straight from the fridgs, but still… ended up going with lighter non-auto alternatives – juniorstar and novo.

Very nice quality pen. I have several and they work very well. The audible click feedback during dosing is nice. They seem to be made with high quality parts and are very easy to use once you get the hang of it. Daro is a very good shop. Shipping has been very fast and I always get email updates through the entire process! 5/5

Love these pens. I now have 4 and they all work great. They are simple and just work. Daro also has the best price with quick shipping. I’ll be getting more when they come back in stock.

Excellent all around pen. Very reassuring building quality, metal screw and casing. Tactile adjustments and button. Would recommend using 31g on these to prevent bottlenecking through the tip but any size will work. Very good price from Daropep, fast shipping!

This one is by far my favorite! Nice consistent spring, nice exact dialing for units, allows using all of the vial without the need of a spacer. Also lets you dial to see how many units you have left when it’s under 60 units (max dose) so you can decide to split doses, etc. Only small downside I would say is that I can’t see the whole typical vial labels from nimbot through the side windows. Not a big deal because I usually label both the vial and the outside pen to always have a clear indication of the label with medication and dosage, mix date.
Other nice thing is the pen allows applying alcohol on not only the small rubber inlet of the vial but also the whole end of the vial which makes me feel like I’ve sanitized as much as I need to for a shot. Some of the other pens have a tiny hole so it’s hard to sanitize just the rubber inlet which is about all they allow access to.

The convipen is my absolute favorite reusable pen. I purchased two of them from Daropep back in February and I have used them eligiously every week since! Customer service is phenomenal and shipping was very quick.

Super impressed with the Convipen from Daro! I purchased 2 and the shipping was fast and customer service was quick from start to finish. I got Convipen wraps too which looks good and makes it easy to know which pen I use for what. This was my very first autoinjector pen, and I found it to be exceptionally well-built and easy to use. Most importantly, it works well for my routine, so much better than manual needles. I highly recommend both the Convipen and Daro Pep to anyone looking for a reliable, high-quality injector.

It’s my first auto pen and I am asking to mysel why I didn’t order 2 or 3, this pen is AMAZING! For sure I will order more in the future! The best pen I used so far. Also I did the order on monday and it was shipped in the same day, and it was delivered in 3 days even using the cheap option. I load it and make it ready to use in the same day after test it. I am in real love with this pen and Daro store.

I purchased two of these and really like them. With being an auto-inject pen, they feel very similar to the ones that branded products use and are very easy to use. I also purchased a rainbow cover for one of the pens and it is stunning!!! Highly recommended!

A very solid Pen. Reliable , accurate and offers a great value.

Ive purchased several of these from Daropep as this is my wife’s favorite pen. Additional plus we purchased some of the pen covers and convis together and he actually installed the covers onto the pen for us. This was a nice surprise when they arrived as it was already installed and ready to go. Great autopen, always works great and is very accurate. I test everything before we put it into use on 5/10/15/20 units and these are always dead on everytime.

Shipped and delivered extremely fast, excellent price, customer service and product. No wonder these pens sell out so quick, they’re excellent.

The Convipen I got from Daro is by far, one of the best pens I’ve ever owned. Consistent dosing, super smooth movement, easy button trigger. Absolutely love the auto-injection mechanism because it saves jerky presses on my part where other pens were just plain trash. Would 100% buy more when I need another pen. Between the Gansulin pen and the Convipen, you can’t do any better.
Alfred B. (verified owner) –
First pen. Shipping was fast, I immediately ordered more pens to try. I’m hooked on them. I did some basic non scientific testing on dosing and it is accurate and very easy to use. Didn’t take long to figure everything out. Now using it daily and so far my favorite. Will be ordering regularly from DaroPep!

I recently bought the Convipen from DaroPep, and everything was super easy and quick! After losing out on my money attempting to buy from another seller, it was so nice to actually buy from a legit seller, and then receive it within a couple of days. I had used pens before, but they were manual. The Convipen does inject faster than what I was used to, so if I had to limit the speed, I would stick with a manual pen instead of automatic. But – for most injections, it’s so nice to just press and hold the button and hear it finish! Thank you DaroPep! I will absolutely be returning for more!

I started with a manual injection pen from Amazon. Figured I could find somthing better. Once I found Daropep I knew I found what I was looking for. I have ordered 4 of these pens so far, worth their weight in gold.
