A three-month supply in the original boxes means three months of flimsy cardboard, awkward stacks on the fridge shelf, and announcing your prescription to every roommate, relative, and guest who opens the door. The MC Dozen 12-pen fridge case holds a full three-month supply of Zepbound, Mounjaro, or Trulicity single-dose auto-injector pens in one clean, discreet case with a real fit. No branding, no labels. Just a solid case that sits in your fridge and minds its own business.

"Quality item that solves the problem of leaving 3 months of meds in the fridge in flimsy boxes."

Karen, verified buyer ★★★★★

The short version

12 pens

A full three-month supply

2 lids

Threaded, one on each end, six pens per side

19 colors

Plus Random and Hodge Podge, in Dots or Hearts

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

Why this beats three boxes

  • Two sides, one case. Six pens load into each side through threaded lids on both ends, so you can work through your current supply without disturbing the rest.
  • A real fit. Our exclusive 3D-scanned saddle system was built from an actual scan of the pen. No rattling, no shifting, no mystery contact between pens.
  • Discreet. No external branding and no labels. Nobody learns anything from your fridge.
  • Built to last. Rigid plant-based bioplastic with a contoured exterior for added strength. Unlike cardboard, it will still be in one piece in month three.
  • Your color, or ours. Pick from 19 colors, or let Derek choose with Random. Hodge Podge mixes random case, lid, and inside colors. Custom colors available on request.
  • Made here. Designed, printed, and shipped from Michigan.

Who it's for

People who think ahead, and anyone on a three-month script who would like their fridge back. The MC Dozen is a fridge storage case. It is not insulated and is not designed for travel or extended room-temperature use. If you need something travel-friendly, check out the MC Cannon or 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 Novo 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.

The lid feels tight or won't screw all the way down. Now what?

The lids should screw on and off smoothly, though they may feel slightly snug right after shipping. That's normal. Don't over-tighten them. If a lid stops early, check the pens: gently rotate and lower each one until it settles into its saddle. Don't force them.

Can I travel with it?

It's built for the fridge, not insulated, and not a cooler. For trips, the MC Cannon or MC Solo is the better pick.

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.

Thanks Again

Fantastically made and will be very useful when I go to maintenance

This is just what I needed. I got the black just because it looked nice and i thought it would be thin and so no light would get in. It was not thin at all since and sturdy but not heavy. So much better then having a cardboard in the fridge. Arrived quickly.

This is the best product!
And...if you take the time to read the very well written instructions..you'll have no problem with both lids, and all the Pens fitting correctly!
It was so easy..and it's perfect!
All 3 months worth of pens contained in this fabulous canister!!

This is a fantastic solution to storing 3 months of Zepbound in my fridge. Much nicer than my previous gallon ziplock bag method!

Such a great idea! Turned out nice, and provides excellent storage for my 3 month supply. Customer service was top notch, Derek answered my questions and addressed my concerns; he even suggested the black color for less exposure to light. The lids can be a little finicky, but as long as you take your time, you should be good!

I ordered the Mounjaro pen holder in black and in grey. They are both beautiful!

The screw lids are both machined / 3-D printed perfectly , and when the canisters are empty, they do completely screw down, leaving no gaps.

My comment to the seller is regarding the need to more precisely machine the depths of the pen inserts, themselves, so that the pens will sit slightly (~2-3 mm) lower within the vessel. Yes, while 12 Mounjaro pens do indeed fit in each canister, as advertised (to be honest, 13 pens actually fit inside each canister—for there is a central hole into which one more pen can fit!), the 6 pens on each side sit a bit too high, meaning that when the lids are screwed on, they hit the protective pen caps, and one dares not continue to screw all the way down--lest one break the pens. So--there's a small 3-4 mm lid gap.

My second one. Good quality. Recommended to friends. Only criticism is their shipping method, I wish they’d use something faster than that bargain USPS method.

I like the container to keep all my pens in but the top is hard to screw on it takes a bit to line uo

Alyssa C.

A great, compact way to store your pens instead of in the box that starts to break down. Saves room in the fridge too!

Just loaded it up in the fridge and got rid of the cardboard boxes. This is a great idea! Bought the grey but it stays in the fridge so color was not really important.

I’m really happy with this 12-pin Mounjaro pen holder! It’s well made, sturdy, and keeps everything organized and easy to access. I especially like that it holds multiple pens neatly without taking up too much space. It’s a simple but very useful accessory and makes storing my pens much more convenient. The quality is great, and I would definitely recommend it!

So enamored with this. It takes up so much less space than the boxes. Love the bright color as it’s easy to spot in my refrigerato and should I need to take it along on a trip, it fits nicely in our cooler! Even ordered a second!
