The Injection Pen Storage Case comes in four sizes: 5, 7, 9 and 12 pens. Count the pens you want in one place and pick the size that matches. Every size is the same height and takes the same pens, so the only thing that changes is how wide the case is.

Case sizes at a glance
| Pens | Width closed | Height closed |
|---|---|---|
| 5 pens | 72 mm | 184 mm |
| 7 pens | 78 mm | 184 mm |
| 9 pens | 93 mm | 184 mm |
| 12 pens | 100 mm | 184 mm |
The 12 pen case is only 28 mm wider than the 5 pen case. All four are made the same way, with a screw-on cover that has a deep thread, so the cover stays closed in a bag.
What fits in each slot
Each pen stands upright in its own slot. Every slot is 21 mm wide and 50 mm deep. The case takes pens up to 20 mm across, including any clip, and up to 178 mm long.
Individual slots keep the pens apart, so they do not knock together, and they are easy to find and easy to count at a glance. The base holds the pens and the cover screws on over them to keep out dust and knocks.

How to choose your size
Match the number of pens
If you have 4 or 5 pens, the 5 pen case is the neat choice. With 6 or 7, go for the 7. With 8 or 9, the 9 pen case. With 10 to 12, the 12 pen case. Spare slots are useful, so if your collection tends to grow, step up one size.
Think about where it lives
The 5 pen case is the slimmest, and the 12 pen case suits a shelf or a desk where you want everything together. All four stand 184 mm tall, so a mixed row of sizes lines up neatly.
Pick a style and colour
There are four styles: Twist, with soft spiral ribs that wrap around the body; Flutes, with classic vertical fluting; Hexagon, a honeycomb of recessed hexagons; and Smooth, with clean, minimal sides and fine grip rings. Choose from Black, White, Grey or Two-tone, a white cover on a charcoal base.
Built to last
The cases are printed in tough PETG, which is easy to wipe clean. Walls are 2.4 to 3.5 mm thick with a solid 3 mm end cap. They are not dishwasher safe. Every case is made to order in the UK.

Other ways to store your pens
One pen on the go: the travel case
If you only need to carry a single pen, the Injection Pen Travel Case is slim at 32 mm across and 215 mm long. The end of the cap has its own screw-lid compartment for 2 to 3 unused pen needles, kept separate from the pen. It is not for used needles. It comes in Black, White or Grey, to match the storage case.
Pens within reach: the desk stand
For a desk, the Injection Pen Desk Stand holds up to 5 pens upright in deep slots, and each slot has an open front so you can see which pen is which and lift it out. A front block of 10 smaller slots takes unused pen needles and other small items. It measures 140 mm wide, 65 mm deep and 102 mm tall.
The 12 pen case and the desk stand are made to match, so you can keep a full set on the shelf and the pens you are using on the desk.
Questions we hear
Do all sizes take the same pens?
Yes. Every slot is the same size in every case, so a pen that fits the 5 pen case fits the 12 pen case too.
Can I mix styles and colours?
Yes. Each case is made to order, so you can choose a different style and colour for each one. A Black Smooth 12 pen case next to a White Twist 5 pen case works well.
How long does an order take?
Dispatched in 2 to 4 working days.
