Thank you for viewing. I am selling these items to organize my materials. This is a set of 100 bell-shaped bead caps. They are a slightly dark silver color. The material is unknown. I appreciate your understanding. Quantity: 100 pieces Height: 5mm Mouth diameter: 8mm If you purchase multiple accessory parts with the #★ mark in the product title, I will deduct the difference in shipping costs. This discount cannot be applied after individual purchases, so please request combined shipping in advance via comments. If you have no questions, you can purchase directly. There is a smoker in my family (we are separating the smoking area), and I have a cat. Shipping is included, and will be sent via Yu-packet Post Mini. I do not accept price negotiations.
