Perfect Refill Set
Perfect refill pack. More than enough quality materials to keep us tumbling rocks for many, many months. Great value and includes instructions, which was very handy as we misplaced the ones that came with the tumbler itself.

Rock polishing supplies
Bought for my son to replenish his rock polishing supplies. Has everything you need at a good quality. You will likely get some of this cheaper elsewhere, but stuck to the branded stuff. Good size of kit that should last a while.

A different idea of polished!!!
I didn’t realise that in the US the use of the term “polished”, actually gives a finish that is closer to a satin finish, than it is to a polished finish.And so I will have to buy some cerium oxide powder to get a truly polished finish.

I was so pleased when I received the box of rock tumbling ingredients and just loved looking at all of the stones
