I made a cold-insulating pet bottle cover using fabric with a forest animal pattern. I used a cold-insulating sheet for the inside of the pet bottle cover. It can keep your drink cold in the hot season and warm in the cold season. It fits 500ml to 660ml pet bottles. The handle is made using black PP tape, about 1cm wide. Size: Approximately 22cm (height) x 13cm (width) 　　　Approximately 6cm (gusset) Each one was made carefully, but it is not a mass-produced item. For those who understand, please consider it (^-^)
