XL Insulin Vial u-500 Protective Silicone Sleeve- Blue

Cant use too large for my insulin vial.

The bag was much smaller than I expected. I was very disappointed. The silicone sleeve was great. I will be returning the bag. It is too bad you don't have some kind of return program like providing a label to return. Thank you

Exactly what we have been looking for!

This sleeve fits perfectly on the vial, providing the protection that we've been looking for! We will be ordering another (just in case!), as well as one for smaller U-100 vials.
