Design: The cover is rectangular and fuzzy, featuring large, embroidered white eyes peeking out from a flap, two rosy cheeks, and a smiling orange mouth.
Material: The outer material is a soft, textured plush or fleece.
Function: It serves to hold a traditional hot water bottle (usually rubber or PVC) inside the cover, providing warmth while the plush exterior makes it comfortable to cuddle and protects the user from direct heat.
Detail: There is a small embroidered detail on the front that appears to say "I ❤️ U" or "I ❤️ J".
