Thank you for viewing! This set is a pair, but may include some size variations. These were made by thinly processing glass rods, cutting them, and firing them in an electric kiln. They are cut with a glass cutter, so some nuggets have cut marks, black spots, or roughness. Some nuggets have different colors on the back. Some nuggets have air bubbles that were originally in the glass. Please refrain from purchasing if you are concerned about these imperfections. Some glass pieces appear 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 5mm wide, or slightly less. The size is measured on the back of the nugget, so it is listed as slightly smaller. We are very sorry, but shipping will be by regular mail. We appreciate your understanding. If you have any questions or don't understand anything, please feel free to ask. 1400 yen #glass #electric kiln #handmade #nugget #earrings #herbarium #seaglass
