Thank you for viewing! This set will be shipped via standard mail. This item is made by arranging two nuggets, which were first created with a burner, and then firing them in an electric kiln. Some of the glass appears to change color under natural light and fluorescent light. Some nuggets are fired with two placed side by side, resulting in a vertically long nugget. Since the finished nuggets are arranged to create the piece, some nuggets that use silver foil may have discolored surfaces. Please refrain from purchasing if you are concerned about this. As it is made of glass, it may break with a strong impact. Since it has been fired, there may be marks on the back. Some items may also contain bubbles. Please refer to the photos in the second and third images for the size. The size is approximately 11mm to 12mm wide and 11mm to 12mm long. The back of the nugget is measured. If you have any questions or don't understand something, please feel free to ask. 1680 yen #glass #electric kiln #handmade #nugget #earrings
