About the product: I purchased this several years ago, but I have similar items, so I am selling this one. It is a type that you use by pouring hot water into it. I have used it a few times, so it is a used item. It is a different color from the pink hot water bottle, which is also listed as new and unused. Size: W approx. 135mm H approx. 195mm D approx. 40mm Capacity: approx. 600ml Weight: approx. 210g Material: Body: Polyethylene, Cap: Polypropylene, Cover: 100% Polyester Heat resistance: 110℃ There is no instruction manual. There are no noticeable defects, but there may be some minor scratches. I washed and sun-dried it before listing. - The photos of the actual product are processed to be as close to the real thing as possible, but please note that the actual product you receive may differ slightly in color. I think it's a little brighter yellow than in the photos. - I plan to ship via Rakuraku Mercari's Takkyubin Compact, but the thickness may be slightly over, so the lid of the box may float a little. I plan to secure the edges with tape. Please consider the above before purchasing. #Hot water bottle #Yutanpo #Cold protection #Heat retention #Bedding
