These are the weirdest tap set ever, but that's exactly what I was lookig for. I needed to thread some 1.2mm threads in a plastic piece and what should I say - it worked! My teeny-tiny bolts go in smooth like butter after tapping, so these measurements gotta be legit.

Worked great for my needs, haven't tried tapping anything very hard yet, just some fairly soft metal. No complaints though, all the sizes seem to be accurate.
