Thank you for viewing! This set will be shipped via standard mail, and the sizes vary. These are glass rods that have been processed and layered with various colors, then fired. They have patterns on both the front and back. They were cut with a glass cutter, so some nuggets may have cut marks, black spots, or roughness. Some nuggets also contain air bubbles that were originally in the glass rods, and some have silver leaf mixed in. Please refrain from purchasing if you are concerned about these imperfections. Some of the glass appears different colors under natural light and fluorescent light. As these are glass, they may break with strong impact. Please check the size using the ruler in the second and third photos. The size is approximately 8mm to 10mm wide. The back of the nuggets is measured. If you have any questions or don't understand something, please feel free to ask. 1100 yen #glass #electricfurnace #handmade #nugget #earrings #herbarium #seaglassart
