StoneCraft 3 + 3 Steps Universal Wet Diamond Polishing Set 7 pcs Set 100mm M14 Thread Aluminium Backing Pad + Bonus Hook and Loop disc

Needs to be used a little initially to get the grinder pads working. A little water is essential - grinders do the job but polishing it until it shines afterwards takes a lot of patience and is quite hard to achieve. Nevertheless, it does the job if you persevere.

Very nice set
