Description
Convipen uses the same platform as the Gansulin. It is a fully automatic, spring-loaded reusable pen designed for standard 3 mL cartridges.
Set the amount in 1-unit increments, up to 60 units, and press the button once. The spring-loaded mechanism completes delivery automatically. Convipen fully depletes the cartridge and prevents setting an amount larger than what remains.
Ships as a bare blue pen only—no travel case or box included.

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
