Kotatsu quilt only ●Waffle batter/Waffle The rough, rich texture gives a feeling of warmth and nostalgia. The outer fabric is a waffle fabric that is not only woven in two colors, but also has a bumpy texture that makes it fun to touch. The underside of the duvet is made of smooth microfiber fabric, which gives you a warm feeling right from the start. ●Plenty of warm padding The filling is made of highly elastic "Toray Mashron R". It is light and voluminous. The center of the fiber is hollow, so it traps warm air and does not let it escape.
