Overview
A nail polish bottle is a small, precise dispensing system. The cap doubles as the handle for a brush that reaches the bottom of the vial, and a wiper insert in the neck strips excess lacquer as the brush is withdrawn, so the user picks up a clean, controlled amount each time.
The heavy base is functional: polish is applied with the bottle standing on a table, so a wide, weighted base keeps it from tipping while both hands are busy.
