This is a set of 90 straps/cords with lobster clasps. There are 10 of each of 9 colors, for a total of 90 pieces. The size, including the lobster clasp, is approximately 60mm to 70mm in length. (There may be slight variations.) As some cords may have defective lobster clasps, we will include 5 extra pieces (color cannot be specified). The items will be shipped in an OPP bag. Thank you.
