Thank you for viewing from among many items. Actual size is slightly over 24cm (suitable for 23-25cm feet). The base color is light blue. At first, you may feel they are tight, but they will naturally conform to your feet. While I make them carefully, there may be slight differences between the left and right. Please understand that these are handmade before purchasing. They can also be washed in a washing machine. In that case, please wash them separately from other items. You may also put them in a laundry net. The advantage of knit material is its soft texture, but it will stretch slightly. Washing will return them to their original width, so then just shape them and hang them to dry. Used clothing etc. are not used.
