The size of one mosaic tile is approximately 1 cm. Please confirm the size! Bulk purchases are welcome! From the second item onwards, there will be a 50 yen discount per item. We inspect the items, but we are selling items that are no longer needed or were not used. Please refrain from purchasing if you are sensitive to imperfections, as this is a personal assessment! I think these can be used for handmade items, cell phone decorations, nail decorations, and more!! If you have any questions, please feel free to comment!
