Review on Exquisite Polymer Jewelry Set in Assorted 0.1-1mm Random Pieces by William Hunter

Definitely inferior metal or alloy of any kind. Also they really should remove the image of a drill used to drill glass beads, that wasn't my aim for them, but it's definitely misleading as none of them are pieces of stone of any kind and you're lucky if they disappear. through plastic, not to mention amber. The bits I show in the picture were broken upon delivery, these are the smallest. Totally baffled as to how they could even be made because others break when you breathe on them. There was a burr on one of the PCB bits, I checked it under a microscope, after dropping a drop of oil on it (without even touching the bit), the spiral broke off under the weight of the oil drop. Just insanely bad Metal.
