The 100% Microplastic-Free Shaker Bottle
Designed with stainless steel where your drink touches, so you can shake without the plastic.
Why Shunya
शून्य
śūnya
SHUN-YAH
zero · empty · void
Shunya takes its name from the Sanskrit word śūnya — “zero,” “empty,” or “void.”
We chose it to represent a simple idea:
Remove what doesn’t belong.
Most shaker bottles put plastic in direct contact with your drink. Shunya was designed differently, using stainless steel where your drink touches.
Better materials. Better rituals.
