What Are The Differences Between The V1, V2, And V3 Pens?
V1 Pen
V2 Pen
V2.5 Slim Hybrid Pen
V3 Pen
V1 pens - (slim body) - made from metal - go up to 80 units - closed cap injection which means you will see and feel the injection (you remove the cap to poke)
V2 pens- - made from metal - go up to 60 units - open cap injection which means you can do the injection with the cap on or off when you use it with the cap on with a 4,5 or 6mm needle tip the cap distracts the nerve endings in your skin so not only will you not see the needle but will feel it much less.
V2.5 pens - (slim body) - made from metal - go up to 60 units and has same dial system as V1 and V3 Pen - open cap injection which means you can do the injection with the cap on or off when you use it with the cap on with a 4,5 or 6mm needle tip the cap distracts the nerve endings in your skin so not only will you not see the needle but will feel it much less.
V3 pens -(slim body)- made from metal - go up to 60 units - closed cap injection which means you will see and feel the injection (you remove the cap to poke)

I’m officially in love with this pen! 💉✨ It does exactly what it promises, and the instruction videos made using it super easy—even for a first-timer like me. The packaging was so thoughtfully done, everything arrived safe, secure, and looking beautiful. You can tell real care went into this. Big thanks to the team—this was a 10/10 experience all around!

The pens are perfect, shipping was timely, the care into hand wrapping is much appreciated, the bonus free extras are also warmly welcomed! I have talked 2 other people into placing orders from you now because of how amazing you folks are! Thank you!

I absolutely love these pens! They have been a game changer in injecting. Faster, easier, less waste and virtually painless. Very pretty colors too! I have 3 so far and would definitely get more. Customer service is great and super fast shipping too.
