content: The set was shipped with a carrying case that was covered in an oil-like substance and either the oil or the case itself smelled horrendous. Also, the punches are very dull and not uniformly sharpened (or dulled, however you look at it). I have difficulties cutting through even thin, soft silicone sheets. Sharpening them with a rotary tool helps, but I feel I shouldn't have to do that with a brand "new" product (which I am sure is actually repackaged). I can't imagine using them for metal, let alone most rubbers. Despite the very affordable price, I would NOT have purchased this set for the above reasons.
