Calamus drinking straw

The design of the “Calamus” drinking straw is based on the natural phenomenon of the vortex. The fine spiral cut inside the glass tube causes any liquid to create a powerful swirling movement when sucked. As is known from the movement sequences in nature, e.g. B. in tornadoes, wild rivers or ocean waves, turbulence increases the intensity of the energy. The fine structure of the mouth-blown drinking straw is designed according to the golden ratio. For easier cleaning, we recommend the drinking straw brush from our range. For children aged 6 and over. In a practical storage quiver.
