Knitted with sock yarn. Washed after knitting. Size is approximately 24cm. A little large. As it is handmade, there may be some size variations, so please understand. You can wash it in the washing machine by putting it in a laundry net. If you are concerned, hand washing is recommended. I wash it in the washing machine. I try to knit carefully, but it is a handmade item by an amateur, so please understand. #socks #handknitted #socks #warmaccessories #winteraccessories #handmade
