These were some of the first dice I bought, and while I was glad to have them, they turned out to be very disappointing.
They state that colors may vary when you buy these kinds of dice, which makes sense, but you'd be shocked how different they look from the pictures. Mine came out with almost no contrasting light and darks, just grey mixed with white, like a Marvel movie that is too afraid to use the color black at all.
They also are incredibly unbalanced, with this set being possibly the most unbalanced out of all of my dice. No matter which kind of die I tested, they all seemed heavily inclined to rolling the lowest numbers available, both with the salt test and just rolling repeatedly.
I'll only plan to use these dice if I DM with new players.
I'd still recommend if you want something to look nice. Even though I was hoping for more contrast in light and dark from my set, it still has a nice smoky appearance, and the customer service is so great that if you get unbalanced dice like mine, they'd likely be willing to give you a full refund or a new set. I just wish the product would match how nice the company is to their customers and promoters.
Glad I decided to buy these, a great addition to my collection. They look even better in person. They arrived with no defects that I can see and the marbling is gorgeous. 10/10, no complaints
