The filling contains things like walnuts, and when heated in the microwave, it can be used as a warm and cozy warmer. This is the price for a parent-child set. If you'd like to buy them separately, please send me a message♪ I've used them several times. Therefore, there are stains and scorch marks on the fabric of the filling. Also, I have washed the outside. Please only purchase if you understand the damage. They have a cute appearance that makes you feel warm just by having them around.
