Revolution Soap Styler Stick, an eyebrow styling product.

This double-ended stick features a soap formula on one side and a spoolie brush on the other, designed to help achieve a "laminated brow" look. It is used to set and shape eyebrows, gripping individual hairs to keep them in place. The product is described as creating a "budge-proof" hold and can make brows appear fuller and fluffier. It is designed for on-the-go use, as it does not require water for activation.
