These tiles have been hand cast into molds, this particular colour is turquoise.
They are sold in 100 gram bags, there are approx. 30 tiles in 100 grams (because they are hand cast, there may be 1 or 2 tiles difference between individual 100 gram bags)
These tiles are super user friendly, they are so easy to cut with a tile nipper, but are strong enough that you cannot break them with your hands.
They do not shatter and leave shards around, and you will not have sore tired hands after working with these tiles.
You need to try them to see for yourself!
