Thank you for viewing! [Product Name] Heat-retaining Electric Hot Water Bottle (with Fleece Cover) [Color] Gray [Size] Approximately 40cm x 30cm [Power Supply] AC100V / 60Hz [Material] Fleece (Cover) [Product Condition] I received this as a Secret Santa gift for Christmas, but I'm selling it because I haven't had a chance to use it. It has not been used, and I only turned it on once to check the operation. However, the outer box and accessories have been discarded, so I've listed it as "Like New." The insulation cover has already been opened, but it is unused. [Product Features] ✔ No need to replace the hot water!
