Séquence The Sequence collection is remarkable for its balance. Its classic tulip-shaped Tumbler finds its modernity in the generous, slender, yet slender design. Its well-proportioned, seamless and not too tall leg is practical for restaurants, wine bars and banqueting. With ten capacities, this complete service allows for optimal tasting of all wines, beers and liquors. It is made of krysta, a material known for its lasting brilliance and transparency.
