Thank you for viewing! I am selling some knitted items. Size: Approximately 23-24 cm (Due to the nature of knitwear, there is some size flexibility). The opening does not feel tight. These are handmade, so please understand. I have several other items, and I offer combined shipping discounts. Discounts are also available for hand-knitted mittens and arm warmers. Please inquire in the comments. 2 pairs: 1800 yen 3 pairs: 2600 yen (For bulk purchases, I will ship via Yu-Yu Mercari Compact.)
