This is just single core wire, as used in the garden, cut and coiled into short lengths. It is not picture wire which should be braided fine wire that makes it more flexible. If you're looking for true picture wire look elsewhere. This was a very expensive way of buying a small coil of ordinary wire!!!
Really poor quality. These boxes have once-only use catches, yet are supplied closed! In trying to open them the hinges just give way, resulting in boxes that need to be taped or glued closed. A total waste of money, look elsewhere.
