For each purchase you will receive a lot of 10-30(you choose quantity in drop down menu) varied assortment of different colored new necklaces/cords for your crafting pleasure.  You will receive an assortment of colors as shown in pictures.  These are made of braided artificial leather and ready for your pendant or new design.  They do have chain extenders on the necklace so you can adjust to the right size for you. They will be from 17-20 inches in length and width is typically 1.5-2mm. I have been a crafter for a long time and found that an assortment of colors is usually better than attaining a large quantity of the same ones. These are silver in color on the lobster claw clasps Thanks for stopping in and have a good day.
