Thank you for viewing! This set is a pair, but may include some slight size variations. This set also includes transparent nuggets. The transparent ones have cut marks on the back. Please refrain from purchasing if you are concerned about this. These were made by cutting thin glass rods 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 this. Some glass pieces may appear different colors under natural light and fluorescent light. As they are glass, they may break with strong impact. Please check the size with the ruler in the second and third photos. The size is approximately 5mm to 6mm wide. 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 would 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
