Perfect for birthdays, Mother's Day, Respect for the Aged Day, Christmas, and of course, as a reward for yourself. Give that special someone or yourself the warmth of a kotatsu.

In that case, please use a lint remover. Sizes: 23-25cm (for women). Men's sizes 25-27cm are available from the link at the bottom of the page. Material: Acrylic, wool, and other materials.
