Silicone glass, meant to use on events, concerts or other shows, with the objective of reduce or replace the use of disposable plastic glasses.
The glass would be made in colours related to the drink's brand, or the event's image, and work as an identifying element or a memory of the event.
Made in silicone, the glass can be flattened and reused, or kept on a pocket or bag until you want to use it again. The material also helps to maintain the drink's temperature.
