(4in D20's and other sizes available in separate listings, 1in, 2in, or 4in) These dice are a huge 4" size measured flat to flat. Made of the finest stress foam, these firm dice can handle all the squeezing, squishing and rolling you can throw at them. Deeply indented numbers on each side in classic and correct RPG style. Painted with high-contrast colors so you'll have no trouble reading these dice after you roll them. Perfect for younger players, or those just young at heart. Take a look at any of your current sets of dice you own. You'll see the same thing, regardless of manufacturer, age, style, numbering or material. They are not well proportioned. Some dice are larger than others. Some smaller, and many radically different across the 7-10 piece set. This difference means that not only are the dice vastly different weights, but they all feel very different in your hand right before you roll. This causes a huge disparity between the force required to roll each die type and therefore causes inconsistency and poor rolling. That last die you rolled that shot across the table or bounced out of your rolling tray, or missed the dice tower opening? That's bad dice proportion in action. In addition to the rolling disparity there's also the visual and hand-feel issues which come into play when rolling dice that are poorly proportioned. They just don't feel good in your hand when rolling and that discomfort means you won't be rolling as well as you could. Less accurate, less consistent and always worse than if you used properly proportioned dice. I know you're going to love these dice. Zucati dice give you and your game the best and most rewarding dice rolling experience possible and make very roll feel great.
