This is a set of three coasters with a beautiful capiz shell luster and gold trim, purchased from a雑貨屋さん (zakkayasan - general goods store) in Cebu, Philippines, along with two mosaic pattern coasters. The mosaic coasters are yellow-based with a gold-like color and are very beautiful. They shimmer with iridescent colors depending on how the light hits them, and I think they will brighten up your table. The back is cork. Capiz shells are famous for being produced in the Capiz province of the Philippines, and are characterized by their thin, translucent white shells. They are often processed into lampshades, accessories, coasters, mobiles, etc., and I often saw them in local雑貨屋さん and souvenir shops. Gold trim coasters: Approximately 7.7cm in diameter, approximately 2mm thick Mosaic pattern coasters: Approximately 9cm in diameter, approximately 4mm thick Unused. I will wrap them in cushioning material and ship them via Mercari delivery. Please understand that these are natural materials and handmade items, so there may be individual differences. Thank you for looking.
