This is a warming product that uses a gelling agent and can be easily heated in the microwave. Body size: 18 x 27cm ☆The box is bulky, so only the main body and the dedicated cover will be sent via Yu-Packet Post. The instruction manual printed on the box will be cut out and included. ☆This is a used item, so the main body has some signs of use, but there are no tears. The dedicated cover is in relatively good condition, but I have a cat, so I do not recommend purchasing this item if you have allergies or are sensitive to such things. ☆I am also selling a Winnie the Pooh Yutapon cover. The main body of this item can be put inside, but combining them would make the shipping cost more expensive, so I cannot accept combined shipping. Please understand. #Yutapon #Yutampo #Yutanpo (Hot water bottle) #Range de Yutapon (Microwave Yutapon) #Kairo (Body warmer)
