I made a cold-insulating pet bottle cover using fabric with a small rose pattern. I used a cold-insulating sheet for the inside of the pet bottle cover. It can keep your drinks cold in the hot season and warm in the cold season. It fits 500ml to 660ml pet bottles. I used a faux leather bag handle for the handle. Size: Approximately 22cm (height) x 13cm (width) Approximately 6cm (depth) I made each one carefully, but it is not a mass-produced product. If you understand this, please consider purchasing it.
