Handmade, simple insulated/refrigerated pet bottle cover (^^). You can use it even as we head into winter. It features a Shiba Inu clasp pattern in light blue. The inside uses a washable, sturdy insulated/refrigerated sheet. It's large enough to hold a warm 440ml or 500ml pet bottle. ◯ Size: Approximately 19.5cm (height) x 8cm (width) x 6.5cm (depth) How about it for those who understand handmade items? Thank you very much m(_ _)m.
