    These people are so friendly! I have 2 scales for setting the tracking force on a phono cartridge, one digital, one mechanical. They disagree by 0.25 gm. Now I know which is true!

    Exactly as expected
    Great price, item weighed well within tolerances. Personally using to verify/calibrate gun powder scales. Would recommend items to others.

    M2 Calilbration Weight - 1 gram
    Item is excellent. Fit right into my set where this was the only weight that was missing. It isn't brass like my set, but it fit the slot perfectly and completes my scale set. A great buy and glad I found this seller on the internet. This was the only place I could find what I was looking for.

    1 Gram Weight
    This is exactly what I was looking for. Found out my scale is off three hundreds of a gram. And now I can prove it. Thank you!
