This is a non-gusseted insulated pouch. It's convenient for carrying ice cool rings, refreezing them, and more, by putting in a cold pack. It has no gusset and is flat, so it won't get in the way in your bag. Although it's a flat pouch, it can also hold a 500ml plastic bottle. (The plastic bottle will be at an angle) Size: Length 22cm Width 22cm Uses a 20cm zipper * The outer fabric (cotton) uses fabric from Decollage. * It uses a washable thermal insulation sheet. Also, the interfacing is made of washable fabric, so it is less likely to lose its shape even after washing. (Please use a laundry net) * Each item is carefully made with care, but please understand that there may be slight distortions before purchasing. #IceRingPouch #InsulatedPouch #DrinkCooling #Decollage #Handmade #FlatPouch #Cooling #Nordic #NordicStyle #Blue #Floral
