Natural and simple slippers made of linen and cotton. The part that touches the sole is made of linen material and feels smooth. The upper lining also uses a cotton-linen material instead of the common non-woven fabric, making these carefully crafted slippers. The sole is made of EVA material, which is convenient because it doesn't absorb water. The official color is brown, but it's a gray-toned brown. The color is exactly as shown in the actual product images. The size is L, with an inner length of 25.5cm (equivalent to 23.5-24cm), but it fit me perfectly at 25cm. I wore them for about a week, but the feel was different from what I expected, so I'm selling them. Thank you for your understanding regarding this used item.
