Cylinders are used in necklaces as spacers what they do is have fewer beads put in your necklace and make the necklace fancier. We sell cylinder beads in 2 which are Gold Finish and Silver Plated. We sell them in 2 sizes which are 10mmX15mm and 8mmX10mm. We sell these cylinder beads in stranded lines. We manufacture these beads in India. These cylinder beads are nickel and Lead-free like all of our other products. We can customize this product and any other product when the customer is buying in bulk. These cylinder beads are e-coated like all of our other product so the color stays on longer and because of the e-coating the color doesn't leave when in contact with skin. We have 3 different design and in one of the designs, there are three colors available which are Gold Finish, Silver Plated, and Gunmetal. We use brass or copper as our base metal for these cylinder beads. You can find this product with many more on www.puritybeads.com.
