To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I really like to color, am very pleased with the product, and I recommend them. The only negative I can say is that the dye is all around not just on the face, so when holding the pieces on the back (non-polished side) the dye powder comes off on your hands slightly.
The product is very sturdy and heavy. But the overall appearance isn't nearly as pretty as the ones that are picture. I bought to use as a gift for science nerd and they liked them but I was a little disappointed with the look of them.
