3-layer dice with transparent top and bottom layers. Pink - Silver Numbering. Neutron Dice are layered dice (3) featuring a shining band of pearlescent color as the center layer, nestled between two clear transparent outer layers! When viewed from the side they appear as 3 layers, but when viewed from the top or bottom, the appearance changes and they suddenly look semi-solid with numbers that seem to float above a colored surface! View them from an angle, and suddenly they look like they're 2-layers! Nothing beats the beauty of a Neutron Die! Each die has the high and low numbers centered on the two clear halves for high-speed number recognition. Every set comes in the GKG Dice Tower Dice Case! Made of high-impact resin, with the same original layering process we invented for Halfsies Dice in 2013 that prevents air-bubbles from forming inside, Gate Keeper Games dice bear the honor of being the heaviest, densest, and most well-balanced resin dice on the planet!
