"Forever20 Eyeliner Shadow Gel" appears to be a misnomer, likely referring to a product from the brand Daily Life Forever52.

The product, often called Long Wear Gel Eyeliner Tattoo, is a highly pigmented, creamy gel eyeliner that is also versatile enough to be used as an eyeshadow. Its key features include:

Long-Lasting Formula: It is designed to be smudge-proof, waterproof, and crease-proof for all-day wear.

Highly Pigmented: The gel delivers intense color in a single application.

Multi-Purpose: It can be used to create precise, sharp lines for winged eyeliner or blended out for a smoky eyeshadow look.
