Thank you for viewing! This set is not eligible for discounts and will be shipped via standard mail. These items are made with a burner and then fired in an electric kiln. Some glass pieces appear different colors under natural light versus fluorescent light. The glass is arranged randomly, so the shapes vary. Some pieces use gold leaf or silver leaf depending on the nuggets used; some nuggets with silver leaf may have a rough surface. Since they are fired, there may be marks on the back, black spots, or bubbles on the surface of some nuggets. Please refrain from purchasing if you are concerned about these imperfections. As these are glass, they may break with strong impact. They are large enough to be used as pendant heads. Please check the second and third photos for the size. The size is measured on the back of the nuggets. If you have any questions or don't understand anything, please feel free to ask. #glass #electric kiln #handmade #nugget #pendant head
