These are handmade parts created using a burner and fired in a household microwave. Mica powder has been sprinkled on, but it's not evenly distributed, so please be aware of that. Because of the mica powder, they shimmer and sparkle beautifully when light hits them ✨ Photos 1-4 were taken in natural light only, and photos 5 and later were taken under fluorescent light. *Please note that some pieces have slight marks from the release paper on the back. Thank you for your understanding. Size: Approximately 6mm~8mm, 56 pieces Please check the back in the 9th photo. Please check the size in the 10th photo. These are handmade by an amateur, so please understand this before purchasing. I am also selling these on other sites, so if they sell elsewhere, I will delete the item even if I have received a comment. Thank you for your understanding. I may not be able to respond to comments until late at night due to work. Thank you for your understanding. *I have dogs and cats at home. Even though I am careful, there may be some pet hair attached. Thank you for your understanding.
