La Rochere's Quessant 10 oz tumbler is inspired by the small wooden slats of traditional Breton canoes found along the coast of Brittany, France. The royal, rich aubergine purple shade adds an elegant pop of color and coastal elegance to casual entertaining. Steeped in tradition, La Rochere is the oldest glass manufacturer in France. Their pieces are fired at high temperatures producing an exceptional quality glass that is crystal clear, durable, and dishwasher safe. La Rochere pieces are renowned for using a traditional molding process which creates their iconic seam.
