Review on M3x0.5mm M4x0.7mm M5x0.8mm M6x1.0mm M8x1.25mm by Jerry Delic

looks like a normal set of left-handed dice. but they are given in some Chinese characters for both the left hand and the thread pitch. I'm sure they will work, but the buyer should be aware that they may be in the wrong desired step when making their selection. I put them in a small plastic box, label them on the outside left and check the pitch before using.
