Please Note: The package only includes 2-pack aluminum foil bags, not including the insulin bottle and cooler case for display. A single aluminum foil protection bag can store 1 insulin pen or 1-3 insulin vials, which is the perfect accessory for the medicine refrigerator

Keep Insulin Safe from Freezing: This insulin protection bag uses thickened insulation foam and aluminum foil to keep the internal temperature stable. When you place the medicine in a cooling device, it will protect your medicine from rapid cooling to freeze, and also slows down the internal temperature rise as the surrounding temperature rises

Keep Vials Safe from Breaking: The aluminum foil insulation bag for medicines is perfect for insulin vials, which can effectively prevent accidental impact and drop, and protect the peptide vials from damage

Ultra-Light & Burden-Free: Weighing only 0.004 lb, it is foldable and doesn't take up much space in an insulin cooler case or travel mug. Ideal for long distance travel, camping, working and cycling.

Reusable & Durable: This insulin pen vial protective bag can be reused, is less affected by the surrounding temperature and is scratch resistant. You can usually put it in an insulin storage case and it can be used for a long time.
