These are colorful sea glass pieces that have been artificially polished for safety. Please understand that there may be scratches, stains, chips, and warps due to the manufacturing process. 【Size】 Approximately 9mm to 2cm (approximate) We will pack them with consideration for impact and waterproofing, but as they are glass products, there is a possibility of breakage or chipping. We will use the anonymous shipping service, Mercari's Yu-Packet Post Mini. Occasionally, pieces with holes may be included, so please check the images. Perfect for handmade crafts!
