We have a few sets of quite large pieces in stock that were originally designed to fit Dal Negro's Olympic Backgammon set (now discontinued) as shown. They are red and greyish-white with the same luscious looking mother-of-pearl effect as the pieces above.
The 44mm Backgammon stones are made of a modern pearlised acrylic material that are nice to the touch and glide smoothly over the Backgammon playing surface. These 44mm Dal Negro Backgammon stone sets are simply the pieces in a bag - there are no dice or other components.
