These are interchangeable sleeves, perfect for fall and winter, as they are warm and airy. Of course, they are washable. The gentle material is safe for those with allergies or atopic dermatitis who apply ointment to their arms. It's difficult to convey the exact color in the photos, but please imagine it's Tanjiro's pattern. It's exactly that checkered pattern. The sleeve width is about 31 cm. The length is temporarily set to 50 cm with red thread. If you want it longer, remove the red thread; it will extend to about 54 cm. The fabric has been pre-shrunk with moisture before sewing. It hasn't been heavily washed, so there's a possibility of slight shrinkage when properly laundered. The gauze has some elasticity, so don't be too concerned. Enjoy it casually with everyday wear like tsumugi, komon, or wool kimonos. The neck and cuffs of a kimono are the coldest areas, so by adjusting the sleeves, you can stay significantly warmer.
