[Recommended as a gift] A great gift for those who suffer from colds or trouble sleeping, or for family, friends, and loved ones. Perfect for birthdays, Mother's Day, Respect for the Aged Day, Christmas, and of course as a reward for yourself after a hard day's work. For those you love, this warm and cozy sleep will feel just like a kotatsu.
When washing, please use a laundry net and wash with a mild detergent. Also, while the material used has excellent heat retention, it is prone to pilling due to friction during wear and washing. In that case, please use a lint remover.
