What's the difference between our F1 and M1 Weights:
1. F1 are more precise than M1, with smaller permission error, F1 applied to the calibration accuracy of 0.01g-0.001g precision balance scales
2. F1 use 304 stainless steel, M1 use 2cr13 stainless steel
3. M1 are with adjust bar (at the bottom of the weights), F1 are without.
