A three-month supply of Zepbound or Mounjaro pens is a serious investment - financially and medically. Storing them in the original prescription box means three months of opening and closing flimsy cardboard, stacking awkward packaging on your fridge shelf, and announcing your medication to every roommate, family member, or guest who opens the door.

The MC Dozen was designed for people who think ahead.

This is a high-capacity dual-sided fridge storage case built to hold a full 12-pen, three-month supply of Zepbound, Mounjaro, or Trulicity auto-injector pens in one clean, discreet unit. Six pens load into each side through dual threaded lids - one on each end - so you always have controlled, organized access to your current supply without disturbing the rest. No branding on the outside. No labels. Just a solid, purposeful case that sits in your fridge and minds its own business.

Inside, the same exclusive 3D-scanned saddle system used across the entire Massive Customs lineup seats each pen precisely - built from an actual scan of the Zepbound and Mounjaro auto-injector geometry. No rattling, no shifting, no mystery contact between pens.

One important note: Zepbound and Mounjaro single-dose pens must stay refrigerated. Per Eli Lilly's official prescribing information, once a pen leaves the fridge it can only be kept at room temperature for up to 21 days - and cannot be returned to the fridge afterward. 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 a travel-capable option, check out the MC Cannon or the MC Solo.

I cannot begin to tell you how much I appreciate you making these. It's Amazing!!!! I had tons of boxes that took up my whole door space..I now have room again!!!! The quality is amazing and the colors are beautiful. If anyone is needing these order them you won't be sorry...I looked for a while for a good quality product to fit 3 months of glp1 shots. Thanks Again

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.

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!

I purchased both the 12 shot and the 4 shot versions fridge cases for Mounjaro and I am extremely happy with the quality of both. I have written reviews on both versions before but I gladly recommend these. Definitely high quality and quick delivery.

Dies not fit Mounjaro pens

Our cases are absolutely compatible with Mounjaro pens. I personally 3D scanned one of the pens myself when making this design, hundreds of our customers are using these with Zepbound, Mounjaro, and Trulicity as they're all the same pen.

I receive a 3 month supply on refills and all 12 pens easily and securely fit in the case. It holds the pens securely and is easy to open. This takes up a lot less room that the boxes do.
