This was knitted last year, so I've lowered the price. Size: Width: Approximately 11-13cm Length: Approximately 187cm It's knitted in a tube shape, so I think it will be warm. You could also put a heat pack inside (^.^) This is a homemade item, so it's not perfect. Please understand. I also have snoods, hand warmers, and wrist covers for sale, so please take a look. I will ship via Mercari Nekopos (anonymous delivery).
