You picked a Blemished item
This version has a minor cosmetic or print defect — a small mark, blemish, or imperfection from the 3D-printing process. It’s offered at a lower price because we can’t sell it as new.
- 100% functional — protects your vials exactly the same.
- Cosmetic flaw only — appearance varies slightly unit to unit.
- Discounted & final sale.
One tall screw-top canister for your whole pen kit: the pen stands in the center socket, nine 3 mL cartridges stand in a ring around it, and a purge post sits in the ring so you can push the air out of a fresh cartridge right there. The tall faceted cap screws down over everything for the fridge or travel.
Key Features
- Center pen socket 20.5 mm (0.81″) wide and 40 mm (1.57″) deep - the pen stands straight, with a slot so a pen with a pocket clip drops in either way up
- 9 cartridge wells - one more than the usual 8-slot pen holders
- Purge post in the ring: press a cartridge down over it to push the air out
- Tall screw cap covers pens up to 172 mm (6.77″) long
- Faceted 12-sided body and cap, 45° screw threads
- Available in Black, Purple, Cyber Green, Cobalt Blue, Red and Hot Pink
What Fits
- Pens: V1 / V2 / V3 style reusable pens and most injection pens up to 172 mm long and up to 20 mm wide where it stands in the socket
- Cartridges: standard 3 mL glass pen cartridges (11.6 mm × 64 mm)
- Purge post: 8.6 mm wide, 40 mm tall
How the purge post works
- With a needle through the cartridge's top seal (crimp end up), set the open end of the cartridge on the post
- Press the cartridge straight down - the post pushes the rubber stopper up and the air out through the top
- Stop when the liquid reaches the top, then lift the cartridge off
The post is 8.6 mm (0.34″) wide and 40 mm (1.57″) tall - about one full 3 mL stopper stroke, so it can't push the stopper into the neck of the cartridge.
Capacity
- Pen + 9 Cartridges: 1 injection pen (up to 172 mm long, 24 mm wide incl. clip) + 9 x 3 mL pen cartridges + purge post
Dimensions
- Pen + 9 Cartridges: 3.04″ L × 3.04″ W × 7.05″ H (77 × 77 × 179 mm)
