Description Liber A is a large glass display unit designed by Luca Papini for Tonelli Design. From a single shape, the Liber system becomes many versatile elements, each with its own function. Liber A is a glass bookcase or showcase with mirrored base, glass sideboard or chest resting on adjustable feet. Optional drawer cassettes are available in white or any RAL color that you would like. (RAL is a standard colour system). It can be brought with either one or two drawers, ans as there is no “back” or “front” to the bookcase it looks fantastic in the middle of a room.
