Thank you for viewing! This is a handmade cover for a Yutapon L-size hot water bottle, made with elegant and calming black (appears as a dark gray or charcoal gray depending on the light) microfiber fabric. The fluffy and soft texture feels comfortable against the skin, gently wrapping around the neck and abdomen, which tend to get cold easily. The simple, solid-color design makes it a warm item suitable for adults of all genders. ・Size: Approximately 26 x 31 cm ・Opening: Overlaps approximately 5 cm, making it difficult for the contents to fall out, providing peace of mind. ・If the size fits, it can also be used as a cover for other hot water bottles or gel warmers. Washable and clean, it's an eco-friendly winter essential that can be used repeatedly. Recommended for home use or as a gift. How to insert: Turn one side inside out and insert the Yutapon into the other side. Then, put the turned-out part back over to smoothly insert it. After inserting, shape it to fit the Yutapon L-size or Oshiri Hot perfectly! ⭐︎Care ・Because the fabric stretches well, be careful when pulling it too hard, as the threads may break when inserting or removing the Yutapon. ・Hand washing is recommended, but if using a washing machine, use a net. After washing, shape it and hang it to dry. ・Be careful of color fading with dark-colored items. ・Please consider this handmade item with the understanding that it is handmade. ⭐︎Shipping ・If you purchase multiple items, they may be shipped together to the same location, but we do not offer combined discounts due to circumstances.
