MC Vault - The Original Massive Customs 5 & 12-Vial Storage Case for 3mL, 5mL & 10mL Medication Vials

Medication vials come in a lot of sizes, and none of them come with a decent place to live. Loose vials rattling around a fridge door, or stacked in the cardboard tray they shipped in, is not a system. It's a scavenger hunt. The MC Vault vial storage case is one case in three vial sizes and two capacities. Pick 3mL, 5mL, or 10mL vials, pick 5 or 12 slots, and pick your color. Every slot holds one vial snugly, in a discreet, durable case with a real fit, as opposed to flimsy cardboard.

Which size do I need?

Every size comes in 5 or 12 slots. Each case fits only the vial size you choose, so measure your vials before ordering. Compounded GLP-1, tirzepatide, semaglutide, peptide, hormone, testosterone, and insulin vials work as long as they match the dimensions for that size. For 10mL cases, the MC Vault 10 Adapter (sold separately) sizes 3mL vials up to the 10mL footprint, so you can store a mix of both in one case.

Why this beats a tray of loose vials

• A real fit. Every slot holds one vial snugly, with no rattling, no tipping, and no contact between vials.
• Threaded lid. Locks down tight enough for the fridge and is durable enough to toss in a bag or carry-on.
• Stays put. A rubber grip base keeps it exactly where you put it on the shelf.
• Discreet. No labels on the outside and no indication of what's in there.
• Built to last. Rigid plant-based bioplastic in 18 colors, plus Random. Custom colors available on request.
• Made here. Designed, printed, and shipped from Michigan.

Who it's for

Anyone on vials instead of pens, whether that's LillyDirect Zepbound vials, insulin, peptides, or hormones, who wants them organized and out of sight at home or on the road. The MC Vault is not insulated and is not an active cooling device.

Quick answers

How do I know which size to pick?

Check the volume on your vial's label, then compare its width and height to the sizes above. Not sure? Shop all cases here, or message us and we'll sort it out before you order.

The lid feels tight. Is that normal?

Yes. It can feel snug right after shipping and loosens with gentle use. Don't force it past its natural stopping point, since that can damage the threads or your vials.

What do Rainbow and Random mean?

Rainbow cases vary in color order and stripe thickness, so no two are identical. Random is our pick from available stock.

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.
