I purchased this at 3COINS. It's a cooling pouch for neck coolers. 【Size】 Approximately 19cm in diameter x 6cm in depth I bought it and used it once, but the size didn't quite fit and it was a little difficult to use, so I'm putting it up for sale. If you don't mind, please consider it. m(_ _)m #3COINS #3COINS #Pouch #NeckCooler
