I was hoping they were more substantial. I like to play with big and heavy stones. But they are beautiful and I will keep them. They are of good quality, just lacking in weight.
Pros
Quality: Chinese characters, Arabic numerals and Latin letters are engraved on the tile; The tile is made of dense, scratch-resistant acrylic, giving it good weight and durability. each tile is 3 x 2.3 x 1.3 cm (1.2 x 0.9 x 0.5 in)
