Thank you for viewing! Please use for crafts and handmade projects. Shell fragments Smooth like porcelain. Please check the size in the image. Washed, treated with boiling water, and then dried in the sun. As these are natural items, there may be scratches, chips, and holes. Items other than the product are for size comparison. I will respond with sincerity and care. Thank you very much. #crafts #seaglass #seashell #herbarium #resin #seaglassart #shellfragments
