Retro Cup Cozy, with Insulated Lining.
I have sewedthese bright colored cup cosy's, to protect your hand from hot liquids in both takeaway and reusable cups. The fabric has a foil insert. Which acts as a protection against heat. But also keeps your drink hot at the same time. The cosy's can be buttoned around the cup. And elastic is used allowing a small amount of adjustment depending on the size of the cup. These are a very useful tool, as they look good and protect you at the same time.
