Purchased last year and only used a few times, so there are no scratches or stains. The length of the zirconia part is approximately 7.5cm. The largest zirconia stone is approximately 1cm. Comb length... approximately 8cm. It's a combination of 11 zirconia stones that appear transparent, but the color changes depending on the viewing angle. The comb part is a slightly brownish color. This comb makes you feel cheerful just by wearing it! *Please note that the appearance may differ depending on the angle. Instant purchase OK! Anonymous shipping.
