This is a Honey Tune pet bottle cover. It's for 500ml bottles, but the image uses a 600ml bottle. It uses a washable aluminum sheet. The inside uses a thermal insulation mesh aluminum sheet. Height: Approximately 21cm Width: Approximately 11.5cm Bottom: Approximately 5.5cm There may be some slight variations. There may be some imperfections such as uneven stitching, distortions, and slight misalignments. The pattern may be cut off depending on the cut. This is a handmade item, so it is difficult to make it as perfectly as a mass-produced product. If you are concerned about minor details or are looking for a perfect product, please purchase a commercially available product. I make each one with care ^ ^ Thank you for your understanding of handmade items. I do not have any pets. Type: Pet bottle cover
