German studio Ding3000 has tweaked different types of drinking glasses to create a family of vessels that takes up less space in the cupboard.
"Looking at our kitchen, we have a lot of individual glasses but usually they do not go well together," said Ding3000 cofounder Carsten Schelling.
"The wine glass can not be stacked into the juice glass and vice versa," he said.
The studio created four shapes of drinking vessels that share the same height and similar widths. A chalice, a stem glass and two tumblers all fit into each other to keep cupboards tidy.
The products are mouth-blown from common soda-lime glass.
Ding3000's portfolio of projects also includes a high-tech version of the first pedalled bicycle and plastic cutlery that clips together to form little sculptures. See more design by Ding3000 »
