DESCRIPTIONS: It is a bag with high standards specially manufactured to ensure the short-long term safe transportation / protection of insulins and medications that need to be transported with a cold chain. Insuport's heat insulation surface is very high. All areas (including under the zipper) are insulated using special insulation materials. It easily carries insulin pen needles, syringes, lancets, swaps etc. enough for two weeks' need. USAGE: Icepacks should be frozen adequately in the refrigerator. The more they are frozen, the lower the temperature they will be preserved. In order to keep the internal temperature of the Insuport Bag at the desired levels and to ensure longer use, please do not open the zipper frequently / do not leave it open. Even a very small opening will cause the inside of the bag to breathe and reduce the storage time.
