Review on 🔬 Hestya Digital Balance Tweezer Test Kit - Calibration, Measurement & Inspection by Adam Nelson

Finally I understand why sometimes my soap never gets hard, the scale I bought wasn't sensitive to +-10g while my others worked great thanks to this little one set of calibration weights that I highly recommend for anyone using a scale, just superb. I wish they came with a bag or box to keep them all together as some of them are really tiny. Feel free to buy them and these pliers came in very handy too.
