Review for 'Blue Diamond Chalk (Box of 2 Cubes)'
I've found this to be much better than the regular Masters and certainly far above Silver Cup. I layer it with Kamui chalk and find the combination works very well for reducing miscues even with very hard and/or phenolic tips. It does seem to be very gritty but that was what I was looking for. I will continue to spoil myself with this more often.
I would recommend this product to a friend.
