I have more than in these photos. In total there are 54 of the thinner ones and another 12 of a longer size. ( in total I have 84 to gift) They make good edging stones ( last really well ) and they can possibly be used for building a wood-fired pizza oven as they are designed to retain heat. I have also used them as foundations for a low garden wall.
It may be worth adding that they are very heavy.
