Pattern: Chacha I accidentally purchased two of the same item and have been storing one at home for several months. I've decided not to use it, so I'm putting it up for sale. It's unused and new, but the top of the outer box is not completely closed by a few millimeters (it was like that from the beginning). Double-layered construction provides high cooling effect, compatible with 500ml and 600ml PET bottles. - Brand: Fuku Fuku Nyanko - Product Name: PET BOTTLE COOLER - Compatible Sizes: 500ml and 600ml PET bottles - Function: Cooling function, double-layered construction - Design: Cute cat illustrations #FukuFukuNyanko #PETBottleCooler #Cooling
