Arc International Luminarc Guinness Gravity Glass, 20-Ounce, Set of 4

Before being able to certify their benefits, before advertising them with a pictogram on their packaging, Luminarc products undergo all sorts of excessive treatment. All the tableware goes through the 'quality qualification laboratory' where all kinds of control and testing instruments designed to replicate daily use are available. Controls are also in place at each step of the manufacturing process in order to intervene on the production line, as early as possible to ensure optimum quality, purity and safety.
