It has a fair amount of stretch. The yarn material is 70% acrylic and 30% wool. The color is black. Because it's black, the pattern is difficult to see, but it's an arm cover with a heart motif. Please check the size in the image. This is a handmade item by my mother, who has been knitting as a hobby for a long time. Since I get cold easily, she uses yarn that she found warm after trying it herself. It doesn't feel scratchy, has a good feel against the skin, is warm, and is light and comfortable. Since the fingertips are exposed, it's useful when working on a computer in the office or using a smartphone! It's a handmade item, so it's not a high-end product like you would buy in a store, but I would be happy if someone who understands this likes it. My friends have told me that it doesn't look handmade. Also, I have received compliments from those who have purchased it on Mercari. We also have different colors, such as mocha, different designs, different materials, fluffy and fluffy white and beige arm covers made of fur material, purple and brown mufflers, and tippets, so please take a look if you like ^_^ You can see all the winter accessories on sale here → #MiyuWinterAccessories Knitting gloves Smartphone compatible Work Winter Fur Faux Fur Fluffy Fluffy Fluffy Fur Hand-knitted Eco Fur New Unused Women Cold Protection Wrist warmers Arm cover Wool Knit Fingerless Summer Winter Cold Protection Cold Protection
