Thank you for viewing. Reason for the defect: Size variations, warping, etc. I made mini beads once using a burner and shaped them into squares. Since each one is handmade, there are variations in shape and size. Please refrain from purchasing if you are looking for perfect beads. Because they are small beads, they may break suddenly. I inspect them carefully, but please let me know if any break. I hope you will use them to make accessories, etc. Since they are glass, they may break with a strong impact. Hole size: 3mm Bead size: The smallest ones are approximately 5mm long and 5mm wide. This set is not eligible for discounts and will be shipped via regular mail. Thank you for your understanding. If you have any questions, please feel free to ask. 1280 yen #glass #burnerwork #accessories #handmade #sidebe
