Odyssey Series 3 Pens LED Insulin Cooler (BC-B004-Navy Blue)
☑️The best feature is simply the QR code! When you activate it, you enter your contact details (📧/📱) there so that you can get your insulin back if you lose it. ADHD buddies understand me 🤗

⁉️I'm also testing whether it really stays cool for a long time and at a constant level! 🧑‍🔬
