Ice Ring Cool Neck Ring SUO LL size. I bought it last year, but it was too big, so I've only used it a few times. I will wash it and give it to you. Inner diameter 14cm Inside circumference was about 42cm. This is a 28℃ type that solidifies at room temperature. *Please refrain from purchasing if you are nervous about home storage. *We do not accept "refunds" or "returns" after the transaction is complete. *We will ship in simple packaging. #HeatstrokePrevention #CoolNeck #Men
