Thank you for viewing! This set will be shipped via standard mail. This item is made by arranging two nuggets created with a burner and then firing them in an electric kiln. Some of the glass appears different colors under natural light and fluorescent light. There are also nuggets that have been fired with two side-by-side, resulting in a vertically elongated 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 9mm to 10mm wide and just under 9mm to 11mm long. The back of the nugget is measured. If you have any questions or don't understand anything, please feel free to ask. 1480 yen #glass #electric kiln #handmade #nugget #earrings
