I thought I would quickly do a review on this which I got from eBay, was actually a UK seller as well so got to me nice and quickly. I have my fingers in the picture as a bit of a size comparison, I imagined that the wheel would be bigger although not sure why as the gems are teeny and thats what I was looking for!
Has a nice range of colours and are all 2mm in size and there is around 2000 of them in the wheel. I got mine from this eBay seller and they were £2.39 which is rather cheap. Now I just have to be inspired to use them!
