Sending 3m cut. When stretched, 10cm becomes about 15cm. Hard type. ⚠️ Please do not purchase if you think it's different from what you expected, as it's rubber. I only have nearly 7000 listings, and I received a bad rating. It makes me want to quit Mercari (ꈨຶ˙̫̮ꈨຶ) ❇️ If you're worried, please buy it at a craft store. Perfect for replacing the elastic on bed sheet pads! #handmade #craftsupplies #handmade #accessories #accessories #craft #flatelastic
