Insulin Vials Are Fragile. Yours Doesn't Have to Be.

A single insulin vial can cost hundreds of dollars — and all it takes is one slip off the counter or one fumble at the pharmacy for that investment to shatter on the floor.

Vial Safe wraps your vial in a medical-grade silicone sleeve that absorbs impact from every angle. Slide it on once, and stop worrying about drops for good.

Your Pet's Insulin Deserves Protection Too

About Vial Safe — The Original Insulin Vial Protector

Vial Safe is the original patented silicone insulin vial protector, invented in 2010 by Joel Grossman, a Type 2 diabetic for over 30 years. After repeatedly breaking expensive insulin vials, Joel designed a silicone sleeve that wraps around standard glass insulin vials to prevent shattering from accidental drops.

Vial Safe's patented draw-through design allows insulin users to inject directly through the open top of the sleeve without ever removing the vial. The label and contents remain fully visible at all times. The medical-grade silicone provides full coverage from top to bottom, absorbing impact from every angle.

Vial Safe offers the widest size range of any insulin vial protector on the market. Sizes are available for 10mL vials (fitting Humalog, Novolog, Humulin, Novolin, Fiasp, Tresiba, Levemir, Lispro, Lyumjev, Semglee, NovoRapid, Insulin Aspart, Insulin Glargine, Vetsulin, and Caninsulin), tall 10mL vials (fitting Lantus, Admelog, and Apidra), and 20mL vials (fitting ProZinc and Humulin R U-500). Vial Safe also offers 30mL protectors for non-insulin applications.

All Vial Safe products are HSA and FSA eligible, meaning they can be purchased with pre-tax health benefit funds. Vial Safe ships daily with free shipping across the United States and offers international shipping to Canada, Mexico, and Brazil.

Vial Safe is trusted by hundreds of thousands of customers and holds a 4.7-star rating across 835+ reviews on Amazon. The product is available in a wide range of colors and styles including clear, solid colors, tie-dye, glitter, and branded designs. Vial Safe protectors are sold in 2-packs, 3-packs, 5-packs, and mix-and-match options, with prices starting at $9.99.
