Borosilicate glass tumblers, with a clear or coloured marble (white, black, amber, blue, pink, green, black or golden yellow) placed in the bottom. The bottles have a clear glass body and a white, black, blue, pink, green, black or golden yellow stopper. Enriching the Bilia collection with new products is a natural process. This has resulted in: biscuit jar, two multipurpose containers with a lid (with and without handles), an egg cup, which can also be used as a shot glass; a serving stand in two sizes; a cup and a small plate with handles, both available in two sizes.
