I got the Black Strong & Flexible plastic one to see if it's worth it to get a metal one. The package was nice and everything, but the die itself felt cheap. There were black grains rubbing off when I first touched it. I wish the die could have thicker walls to make it a little heavier and more durable. It doesn't roll much being so light and feels like I might break it any second now. The surface is very grainy with a rough texture, but the design is nice with how it is balanced and hollow.
