Stack Up Stack Up: This is a collection of tumblers with a timeless profile that will fit perfectly in bars and restaurants where the service is very rhythmic and intense. The conical shape of the Stack Up collection may seem simplistic, but it reveals all its strengths when used. This shape is precisely the key to its stackability, supported by the small step hidden inside. All the cups meet the requirements of mechanical and thermal shock resistance, and thus allow a safe service. Thus, the 4 highballs can be used to serve a classic or revisited cocktail, and the 4 old fashioned ones highlight the warm tones of the spirits. Tip: don’t hesitate to play with hot drinks with this attractive and practical line.
