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 thong appears yellow in the photo, but it is actually orange-beige. Size is M, suitable for approximately 23-23.5cm. 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 loosens or feels tight after wearing for a while, please untie and retie the thong on the underside. These are handmade items, so they are not perfect. Please understand this before purchasing. Please refrain from purchasing if you have a dog allergy.
