I haven't used the necklace, bracelet, and brooch much, but there may be some signs of wear due to age. I couldn't tell much with the naked eye. Necklace Both the chain and the balls are black, with only a small diamond-cut-style decoration at the base of the balls, which is not very noticeable and I think it's good. Magnetic Bracelet This bracelet uses hematite and red beads. It has a wire inside and becomes round while attaching magnetically. Brooch It has a slightly flashy design. How about it for those looking for chic accessories that aren't flashy, those who like flashy brooches, those who want a magnetic bracelet, those looking for inexpensive accessories, etc.?
