※ This listing is for the cover only (no hot water bottle). The fabric is fluffy and feels very nice. 100% polyester. Machine washable in a laundry net. The hot water bottle was used in another case, so this cover has hardly been used. *Please note that only the outer dimensions can be measured. Approximately 28cm (11 inches) tall x 28cm (11 inches) wide. Zipper width is approximately 23cm (9 inches). Instant purchase is welcome! #hot water bottle #cover #miscellaneous goods #cold protection #winter #beautiful item #fluffy #accessories #beige
