These are lightweight, quick-drying waraji-style sandals made by wrapping a nylon core with yukata fabric. Although made from recycled fabric, they are new as sandals. The color of the thong is closest to the fourth picture. They are recommended for those who wear approximately 24-24.5cm (US size 7-8). To wash, hand wash and put in a net for spin-drying, or use the delicate cycle in a washing machine with a net. Please wash separately as there is a risk of color bleeding. If the thong becomes loose or tight after wearing for a while, please untie and retie the thong on the underside. These are handmade, so they are not perfect. Please understand this before purchasing. Please refrain from purchasing if you have a dog allergy.
