I made a cover for a hot water bottle to be used in the cold season. The outer fabric is flannel and the lining is fleece, making it smooth to the touch. ⚠️Hot water bottle used as a reference: 27cm (H) x 23cm (W) x 8cm (D) (Although there is no indication, I think it's 2.6L) It should fit hot water bottles smaller than this. ⚠️This is a handmade cover only, for use with your own hot water bottle. I make them carefully, but please understand that there may be some distortion, misalignment, and size errors. Please understand this is handmade before purchasing. ◯ Fabric Outer fabric: Flannel cotton Lining: Fleece polyester String: Cotton ◯ Please refrain from price negotiations. ◯ It will be folded in four and shipped in a Yu-Packet Mini envelope. ◯ This product is thick, so bundle discounts are not available. ◯ Immediate purchase is welcome!
