Choices of grit GC36, GC60,GC100

I purchased a mixed box of the blocks.
As I checked out on-line I noticed the shipping did not increase much. I added several other item with only a few £pound extra or Zero. Nicely packaged box.
GC36 sure did remove material well.
GC60 gave a good finish
GC100 very fine and took hardly anything off
A great choice of handy blocks
cleaned up my Bricks and stone window sills on the front of my house

    never used one before 2018-12-10

      Does the job!

      does the job as expected.
      Takes a while to rub stone in to polished slury to get a good buff finnish. The running brick/ block opens up the more you uses it.
