I made a handmade cover for "Azuki no Chikara" neck and shoulder warmer. It's made of stretchy, soft fabric. The material stretches well horizontally. I made it to fit my own "Azuki no Chikara," so there might be some variations. The cover tends to stretch out with repeated use, so I added elastic to the opening. You cannot microwave the cover with the main body inside. When putting it on, place the main body on top of the cover and insert it in the order of the top half, then the bottom half. The corners, which are U-shaped, are reinforced with two stitches. You can wash it in the washing machine using a laundry net. When drying, it tends to stretch horizontally, so it's recommended to hang it vertically. There may be traces of purple pen (disappearing ink) or temporary adhesive, but they will come out in the wash. This is a cover only sale. These are sample images. They are made of the same fabric, but the pattern may vary. The colors may be slightly different. Please refrain from negotiating the price for a single item. If you purchase multiple items that can be packaged together, I will discount the shipping cost.
