Thank you for viewing! This set is not a pair. There are variations in size. Reason for being slightly "as is": These are not natural sea glass. They are machine-cut, so some may have imperfect cuts or black spots. Please refrain from purchasing if you are concerned. Glass rods were thinly processed, cut, and fired in an electric kiln. They are cut with a glass cutter, so some nuggets may have cut marks, black spots, or roughness. Nuggets with different colors on the back are also mixed in. Please refrain from purchasing if you are concerned. Some glass appears to have different colors under natural light and fluorescent light. As these 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 4mm or 5mm wide. The measurement is taken from the back of the nugget, so the size is listed slightly smaller. I am very sorry, but I will ship via regular mail. Thank you for your understanding. If you have any questions or don't understand anything, please feel free to ask. 1499 yen #glass #electric kiln #handmade #nugget #earrings #herbarium #seaglass art
