PET Monomaterial Airtight Twist-Up 3.06mm Eyeliner & Brow Pencil with Integrated PET Sharpener

What this packaging is

Built entirely from a single PET material, this twist-up eyeliner and brow pencil delivers an airtight mechanism that preserves formula integrity from first use to last. The 3.06mm bullet tip supports precise application for eyeliner, lip liner, and eyebrow work, while the integrated PET sharpener keeps that tip consistently fine without requiring a separate tool. At 130.8mm tall and 9.0mm in diameter, the cylinder profile is slim and ergonomic. Manufactured in China, the monomaterial PET construction simplifies end-of-life recycling, a genuine structural advantage for brands building more responsible product lines.

Why brands choose this

• Built-in sharpener removes a consumer pain point: The integrated PET sharpener means consumers always have a precise tip on hand, no separate tool needed. That small convenience drives satisfaction and positions the product as a thoughtful, complete experience at point of use.
• Monomaterial PET construction supports recyclability claims: The full PET build, pencil body and sharpener alike, means no material separation at end of life. For brand teams navigating recyclability commitments, this is a structural choice that backs up sustainability messaging without greenwashing.
• Slim cylinder format fits the precision beauty ritual: At 3.06mm and 130.8mm tall, the pencil's narrow profile is calibrated for the fine-line work consumers expect from eyeliner and brow products. That format match reinforces consumer confidence and reduces the learning curve for adoption across multiple liner categories.
