Set of 5 round coasters woven from natural materials. Size: Outer diameter 10cm, thickness 5mm (slight variations may occur) Weight: Approximately 15 grams per coaster Material: Balinese Ata grass, a very lightweight and high-quality material. Each one is handmade, so there may be some unevenness on the surface. This adds to the character of the product. We hope that those who appreciate this quality will purchase them. These are new, as they have not been sold in stores yet. They will be shipped via Yamato Transport (Nekopos), so they will be delivered to your mailbox like regular mail. Thank you for viewing.
