Frequently Asked Questions
Q: What makes the O TWO Eyeliner Stamp Pen different from a regular eyeliner?
A: Unlike a standard eyeliner pen, the O TWO Eyeliner Stamp Pen features a dual-ended design with a pre-shaped wing stamp on one end and a fine-tip precision liner on the other.

Q: How do I remove the O TWO Eyeliner Stamp Liquid Pen?
A: Use a gentle oil-based or micellar water makeup remover. Soak a cotton pad and press it gently against the liner for a few seconds before wiping away to avoid tugging on the delicate eye area.
Q: Is this eyeliner suitable for beginners?
A: Absolutely. The wing stamp end is specifically designed to take the difficulty out of creating even, symmetrical cat-eye wings. Simply press at your desired angle and connect with the liner tip — no prior experience needed.
