I received it today. The balls are okay, heavy, and they do their job, but the design is already faded. I don't know if they will withstand the test of time, but they seem relatively sturdy. Apart from that, the box is cheaper than cheap of the cheapest. It is evident in the photos I uploaded. The box could have been something slightly better for its price. The store sent the product pretty quickly and I doubt the quality of the product is their fault
