I made a cold-retention pet bottle cover using fabric with a cat pattern. I used a cold-retention sheet for the inside of the pet bottle cover. It keeps your drinks 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 tall, 13cm wide 　　　Approximately 6cm depth Each one was made carefully, but it is not a mass-produced product. If you understand this, please consider purchasing it. (^-^)
