Fun but poor quality
Fun novelty toy but breaks very easily as it is a soft mineral. I also was not happy that the item was not completely translucent due to impurities. Because of this, you could kind of see words appearing on the surface but it definitely had a large effect on the clarity. Because the quality of the product is questionable I would most likely not buy this product again.
