For 130 years, Anker stones have been made by hand in Rudolstadt / Thuringia according to a traditional recipe. They are the oldest system toys in the world.
100 percent natural materials fulfil the strictest ecological criteria. The stones consist of chalk, quartz sand, colour pigments and linseed oil. ANKER STONES are unique because they are made exclusively from natural materials, because they smell mysteriously of linseed oil and because they hold together without studs and glue.
