These luxury backgammon counters are made from Galalith, which is a traditional synthetic plastic made by combining milk casein and formaldehyde. Its name is derived from the Greek words \'gala\' (milk) and \'lithos\' (stone), thus a form of milk is used in the process. This gives the finish a really luxurious semi-opaque look with a sublime depth of colour. This particular set is ivory and a warm grass green. It\'s hard to fault these exquisite counters, polished, balanced and sound wonderful when striked together during play.
