From Berlin–based NEW TENDENCY, the RIEN drinking glasses are designed to appear delicate while maintaining stackability. This set of four glasses is made from borosilicate glass, which is a glass that was originally developed for scientific laboratory equipment. The result is a glass that is more durable than traditional drinkware, and is also heat resistant. Each stackable glass features a cone-shaped, curved base that gives the RIEN glasses their appealing form and distinctive functionality. The glasses can be used as water glasses or for cocktails, wine, or juice. Their simple shape makes them an excellent choice for everyday drinking, but the glasses are equally suitable for a dinner party or special occasion.
