Custom Insulin Case: A Hard Case Built Around Your Pens and Vials

Updated October 4, 2026 · 2 min read

Short answer

a custom insulin case is a hard organizer designed around the pens, vials and supplies you carry each day. In the PeptideCase™ builder you add a pen tray, vial pockets and flat bays, choose a latch and color, and check the 3D preview before ordering.

Why a fitted case?

Soft pouches let pens and vials knock together and slide around. In a fitted hard case every item has its own place. That protects them in a bag and makes it obvious when something is missing.

Design your case in a few minutes

Add what you carry, pick a color and latch, and check it in 3D before you order.

Build it around your daily kit

  • Pen tray: a raised, fitted tray so pens lie flat and lift out easily.
  • Vial pockets: 10 mL, slim 10 mL or 3 mL pockets, as many as you need.
  • Flat bay: for pads, wipes or a small meter strip pack.
  • Custom space: enter any item's width, depth and height and the builder fits a pocket for it.

Optional temperature window

Add a clip-in window to the lid for a small digital thermometer. You can then read the temperature inside the case at a glance without opening it.

Easy to tell apart

Add your name, initials or an icon to the lid, and choose a case color that's easy to find in a bag.

Frequently asked questions

Can I fit pens and vials in the same case?

Yes. Combine a pen tray with vial pockets in one design.

Does the case keep things cold?

No. It's a protective, organized hard case, not a cooler. The optional window lets you read a thermometer inside it.

Can I order the same case again later?

Yes. Your designs are saved under "My Custom Cases" for one-click re-ordering.
