ND Calamus Straw


The vortex, a natural phenomenon, underlies the design of the “Calamus” drinking straw. Because of a fine spiral cut into the narrow glass tube, any liquid that passes though it acquires a powerful vortex motion.


As seen in nature – tornadoes, for example, or wildly-flowing rivers or ocean waves – the vortex action increases the intensity of the energy.

The delicate structure of the hand-blown drinking straw takes its shape from the golden ratio.

For ease of cleaning, the straw comes with a bottle brush of the appropriate size.

For children over 6 years.
