Great Product! I use this in my Dungeon Crawl Classics Game. DCC uses a die chain mechanic which can move the die roll up or down a scale of dice sizes/types. All of the necesary dice are on the cards which makes it very easy to resolve a roll, in addition the deck takes up less space behind the GM screen. This is particularly helpful at convention games. I highly recomend this product.
