Each knob came individually wrapped in its own "jewelry" box. The quality is superb. Did not notice any imperfections on the metal part as reported by other shoppers. There is an inscription on the crystal part of the knob, perhaps to certify that it is. However, these knobs looked a bit over the top in my powder room. I felt that for this to work, the powder room and the vanity had to be fancy.  A side note: this knob will puncture the vanity in 2 places. One of the back nails is to keep the knob in place and not allow it to rotate.
