Thank you for viewing! Shipping will be via standard mail. Thank you for your understanding. These items are made by processing rods created with a burner and cutting them into small pieces, then firing them in an electric kiln. These nuggets are made by mixing transparent blue and purple glass. Some nuggets have a stronger blue hue, while others have a stronger purple hue. We hope you appreciate this as part of their individual character. Some glass colors appear different under natural light and fluorescent light. Please refrain from purchasing if you are concerned about this. As these are glass, they may break upon strong impact. Since they are fired, some items may have marks on the back. Some items also have bubbles. Please check the size using the ruler in the second and third photos. The size is approximately 13mm to just under 15mm wide. 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
