SIGNI 11Pcs Diamond Polishing Compound Lapping Paste Syringes 0.5 to 40 Micron 5 Gram for Polishing Metal and Jewelry (Oil Based)

ممتاز

Ok so I used and the 40 micron is finer than the 0.5 ,idk what's up with the 0.5 but wasn't good

Worked exactly as expected, make sure to use a new applicator for each of the abrasives or risk cross contamination, would buy again.
