I made a cold-insulating pet bottle cover using Japanese-style patterned fabric. I used a cold-insulating sheet on the inside of the pet bottle cover. It keeps your drink cold in the hot season and warm in the cold season. It fits 500ml to 660ml pet bottles. The handle is made of black PP tape, about 1cm wide. Size: Approximately 22cm tall, 13cm wide Approximately 6cm depth I made each one carefully, but it is not a mass-produced product. If you understand this, please consider purchasing it. (^-^)
