Size: Approximately 22 x 33 cm These are approximate dimensions, so please consider them as a reference only. (^人^) This item is made with a small 1.7L hot water bottle as a reference. Please check the size of your hot water bottle (length, width, etc.) before purchasing. The outer fabric has a thin red & pink star pattern. The lining is also thin with a cream-colored floral pattern. Acrylic fabric is sandwiched in between. It's not very thick, so please be aware of this if you are looking for something thicker. ※ The lining and the intermediate acrylic fabric are recycled fabrics, so please refrain from purchasing if you are at all concerned. ※ If you look closely, you can see the pattern (red and black checkered pattern) of the intermediate acrylic fabric through the outer fabric. Please understand. As burns at low temperatures are a concern, we recommend using this cover and then wrapping it with a bath towel or similar. ※ The actual colors may differ from those in the photos. This is not recommended for those who are particular about subtle colors or textures. Some recycled fabrics are used, and this is a hobby-level amateur handmade item, so it is not a perfect product. Please refrain from purchasing if you are concerned about details such as the materials used, sewing, or packaging materials. We will pack it as compactly as possible, so the packaging is simple, and it will be compressed, which may cause wrinkles. We are looking forward to your consideration and purchase if you are a kind person who understands the above matters.♡
