SmoothStraw is an ergonomic silicone straw tip that fits over your existing straw. It expands the contact area on your lips, reducing muscle strain and preventing the formation of lip wrinkles (often called "straw lines" or "smoker's lines") from repetitive pursing.
Traditional straws require you to purse your lips tightly, engaging the orbicularis oris muscle repeatedly. Over time, this creates fine lines around the mouth. SmoothStraw's wider, softer silicone tip distributes pressure evenly and allows a relaxed seal, eliminating the need to purse.
SmoothStraw fits most standard straws including Stanley cup straws, Yeti straws, metal straws, glass straws, boba straws, and standard plastic straws (6-10mm diameter). It works with both hot and cold beverages.
