I made a cold-insulating pet bottle cover using fabric with a strawberry and ribbon pattern. I used a cold-insulating sheet for the inside of the pet bottle cover. It keeps drinks cold in the hot season and warm in the cold season, making it convenient to carry. It fits 500ml to 660ml pet bottles. The handle is made using black PP tape, approximately 1cm wide. Size: Approximately 22cm (height) x 13cm (width) 　　　Approximately 6cm (depth) I made each one carefully, but it is not a mass-produced item. If you understand this, please consider purchasing it (^-^)
