Brand new, unused. These are very beautiful, high-quality tiles from Nagoya Mosaic. The mix of glass and marble is wonderful and gives a luxurious feel (*^^*) There are 324 tiles (18 tiles x 18 tiles). *The photos are examples, so the arrangement of glass and marble may vary depending on the sheet. Shape: 15-sided [Net-mounted on the back] Tile size: Approximately 30x30mm, thickness: 8mm This is my first time using Mercari, so I'm not used to transactions.
