Size: Approximately 22 x 33 cm These are approximate measurements, so please consider them as a reference only. (^人^) This cover is made with a small 1.7L hot water bottle as a reference. Please check the size (length, width, etc.) of your hot water bottle before purchasing. The outer fabric is a thin navy blue with a retro pattern and lace♪ The lining is quilted. Because it's thick, the opening won't close completely. Please check the photos. If you are concerned, please refrain from purchasing. As burns from low temperatures are a concern, we recommend using this cover and then wrapping it in a bath towel or similar. ※ The actual color may differ from the photos. This is not recommended for those who are particular about subtle colors or textures. The outer fabric has been stored for many years, so it has some fading, and it's a handmade item made by an amateur, so it's 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 look forward to your consideration and purchase if you understand the above.♡
