A three-month supply usually means a stack of cardboard boxes eating an entire fridge shelf. The MC Dozen Slim 12-pen fridge case holds twelve Zepbound, Mounjaro, or Trulicity single-dose auto-injector pens standing upright in a case that's tall and thin by design, so it fits in the door of most fridges, right where nothing else wants to go. Your shelves stay free, your pens stay put, and nobody grabbing a drink gets a look at your pharmacy haul.

"It keeps my injections in one place, don't have three medication boxes taking up space in the fridge. Very easy to place and retrieve the Pens when needed. Definitely recommend it!"

The short version

12 pens

A full three-month supply, six from each end

1.85 in

Wide. 7.25 in tall x 10.5 in long (46 x 183 x 266 mm)

13 colors

Including two-tone Oreo, Go Blue!, and Creamsicle

Fits: Zepbound, Mounjaro, and Trulicity single-dose auto-injector pens. Does not fit: KwikPens, vials, 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 a stack of boxes

  • Lives in the door. A tall, narrow footprint built for fridge door shelves, not your main shelf space.
  • Magnetic sliding lids. Two lids cover the openings and latch shut with hidden magnets, so the case stays closed when you pull it out and there are no loose caps to lose.
  • A real fit. Every pen drops into its own precision cradle modeled to the actual pen dimensions. Nothing rolls, rattles, or wanders off.
  • Discreet. A clean, solid case that gives away nothing about what's inside.
  • Durable. Rigid plant-based bioplastic that shrugs off fridge humidity and daily handling. Cardboard, famously, does not.
  • Built for the 3-month script. Designed for the move from monthly to quarterly refills.
  • Made here. Designed, printed, and shipped from Michigan.

Who it's for

Anyone who just switched to quarterly refills and opened the fridge to find three boxes where the leftovers used to be. This is a fridge storage case. It is not insulated and is not a cooler. If you only need to hold a month at a time, the MC Slim holds four.

Quick answers

I can only fit six pens. What am I missing?

The case loads six pens from each end, so slide open both lids. If a pen doesn't drop all the way in, gently rotate it and lower it until it settles. Don't force it.

Will it fit my fridge door?

It stands in the door of most fridges, but door shelves vary. It's 1.85 in wide, 7.25 in tall, and 10.5 in long, so measure your door shelf before ordering.

Will it fit my pen?

If you use Zepbound, Mounjaro, or Trulicity single-dose auto-injector pens, yes. KwikPens, vials, 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.

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.

I love my case! I love that it is made in USA. Product is just as advertised and received in less than a week. I have ordered another case and after telling my daughter about the case, she has ordered too! I love supporting this small business!

Came across an add for this and decided to give it a try. I purchased the 12-pen slim fridge case in marine blue and it looks awesome. I get a 90-day supplly, so this is perfect for me. Takes up much less space in the fridge and I like that the lid for each side is numbered (1-6/6-12). Amazing craftsmanship and like the idea of helping a small business owner, who provided direct contact information with the item in case their were any issues. Supply happy with my purchase!

This fridge case is amazing! Very well made and my pens fit perfectly! I had 3 boxes of in my fridge taking up so much room. Now they are all conveniently in 1 container. I love the product and have already recommended it to others. Now I need one for my Humalog pens.

Bought 2 of the 12 syringe cases, one for my wife and one for myself. They are awesome and we now have room in our veggie drawer

Great way to store pens and avoid multiple boxes in your fridge. Pens fit perfectly and container is super strong so there is no worry about pen damage. Only small nit is that the lavender color is definitely a darker purple vs a pastel, but i still love it!

Great case for storing up to 3 weeks of Mounjaro pens. Perfect size and takes up very little space in refrigerator. Well made and sturdy. Magnets in lids keep all pens safe.

This works very well for my injectables, fits perfectly where I wanted it to fit, like the the interior design is as great as the external, you can tell lots of thought has gone into the design of this product. The fact that each vial is held securely makes a difference.

It keeps my injections in one place, don't have three medication boxes taking up space in the fridge.

Very easy to place and retrieve the Pens when needed.

Definitely recommend it!

Each script has a label attached stating how many refills are available. The case holds the pens just fine however, after removing them from the box there’s no place for the script label reminding the patient how many refills are left. Suggest adding a way .. maybe external pouch to place that label
