Review on 🔍 Precision Calibration Weight: American Weigh Scales Ensures Accurate Measurements by Tay Fair

There's not much to say about something that just has to exist in order to work. I tested them on 2 scales and got the same result, as far as I can tell they are the right weight (or at least the same weight). to the elements. I don't know if it matters. I use them to calibrate my jewelry scales. Caution: Buy a scale first and see what weights you need to calibrate. I thought mine only needed 100g weight but it calls for 100g and 200g when you do the test so I just bought 2 of these. Pros: Seems to weigh 100g as advertised.
