Thank you for viewing! This is a pair of hand-knitted slipper-shaped room shoes. They are designed for those with shoe sizes of 23-24 cm. They have a four-layer sole with a thin plastic board in between. From the top: acrylic yarn, acrylic yarn, plastic board, and acrylic yarn. Please be careful as folding them in half may break the inner board. If the board breaks, it may injure your feet, so please refrain from using them. They do not have non-slip soles, so please be careful when wearing them. Material: Acrylic Size: Sole length 23 cm, sole width 9 cm. The instep part is elastic. After completion, they are hand-washed and dried before packaging. I knit them with care, but they are within the range of handmade quality. Thank you for your understanding.
