The box your pens shipped in was never meant to be opened week after week, tossed in a bag, or shoved to the back of a fridge shelf. It's flimsy, it broadcasts exactly what you're storing to anyone who opens the door, and it falls apart long before your prescription runs out. The MC Cannon 4-pen storage jar holds a one-month supply of Zepbound, Mounjaro, or Trulicity single-dose auto-injector pens in a round, discreet jar with a threaded lid and a real fit, as opposed to flimsy cardboard. It was built for people who use their case.

"The container is perfectly designed to fit the Mounjaro pens... The construction is solid. The top fits well. It is so much better looking in my fridge than the flimsy box the meds come in."

Phil, verified buyer ★★★★★

The short version

4 pens

A one-month supply

Threaded

Screw-on lid that won't pop open in a bag

24 colors

18 solids, 5 duals, and Random

Fits: Zepbound, Mounjaro, and Trulicity single-dose auto-injector pens. Does not fit: KwikPens or Wegovy pens. For those, see the MC Kwik for Zepbound KwikPen, the MC Kwik for Ozempic, or the MC Slim for Wegovy.

Why this beats the original box

  • Locks down tight. The threaded lid screws on securely, so you're not wondering whether it popped open somewhere in your bag.
  • A real fit. Our exclusive 3D-scanned saddle system was built from an actual scan of the pen. Every pen seats correctly, stays put, and comes out cleanly. No rattling, no shifting, no mystery scratches.
  • Fridge or road. At home in the fridge, packed in a cooler for a trip, or tucked into a carry-on.
  • Discreet. No external branding and no labels telling everyone what's inside.
  • Built to last. Rigid plant-based bioplastic that holds up to weekly use far longer than a cardboard box ever will. Custom colors available, just send a message.
  • Made here. Designed, printed, and shipped from Michigan.

Who it's for

Anyone who wants one case that works in the fridge and on the go. The MC Cannon is not insulated and is not an active cooling device. If you want a slimmer fridge-only option, check out the MC Slim. For carrying a single pen, check out the MC Solo.

Quick answers

Will it fit my pen?

If you use Zepbound, Mounjaro, or Trulicity single-dose auto-injector pens, yes. KwikPens and Wegovy pens need their own cases (linked above). Not sure which pen you have? Shop all cases here, or message us and we'll sort it out before you order.

How tight should the lid go?

Snug is plenty. Don't over-tighten it. If the pens don't drop all the way in, gently rotate and lower each one until it settles into its saddle. Don't force them.

Does it keep my pens cold?

No. It protects the pens, but it isn't insulated and isn't a cooler. For trips, pack it in a cooler and follow your medication's storage guidelines.

How do I clean it?

Hand wash with cool water and mild dish soap. It's not dishwasher safe, and it shouldn't be left in a hot car or direct sunlight.

Storage case only. Medication not included. Always follow your healthcare provider's instructions and the manufacturer's storage guidelines for your medication. Zepbound, Mounjaro, and Trulicity are trademarks of Eli Lilly and Company; Ozempic and Wegovy are trademarks of Novo Nordisk. Massive Customs is not affiliated with or endorsed by these companies.

Fantastic design! The container is perfectly designed to fit the Mounjaro pens. The divot in the center so that you can lift out a pen without pulling the grey cap off the pen is a very well-thought-out design.

The construction is solid. The top fits well. It is so much better looking in my fridge than the flimsy box the meds come in.

Works the same and as well as the single shot case. I wouldn’t travel with this one.

Whoever invented this had a great idea for storing my Mojarro, easy to store and easy access for one. I have to take my weekly shot. Love the product.

Hey Charles! Thanks for the review! I actually came up with this design 100% in house - its just me working here at the moment so I appreciate the kind words! Glad you like your new case!

Slots in the container are a perfect fit and the container fits perfectly in the door of my fridge. I'd been fighting with how to beat store the Mounjaro pens for months and they were driving me nuts being so awkward and getting in the way no matter how I stored them. This brilliant little creation was the perfect solution.
