The Circu-Square Straw / product design

The Circu-Square Straw

The circu-square straw has the typical circular straw you're used to on the upper edge of the bend, but transforms into a square shape on the longer edge below, allowing air to pass through standard circular holes. This prevents the regurgitation of liquid through the straw due to an increase in air pressure.
