DupakSYS Nail Oil Pen 100 Pack 3ml Transparent Twist Brush-Tip — Leak-Resistant Travel Applicators

These disposable twist pens come in a bulk pack of 100 transparent tubes with 5 sheets of 120 adhesive labels for organization. Each lightweight pen holds approximately 3ml, features a soft white brush tip for smooth application, and seals to prevent spills during travel. The pens accept a wide range of non-corrosive cosmetic liquids, making them a flexible solution for home use, professional services, sampling and on-the-go touch-ups.

How do I fill and use a DupakSYS brush-tip pen?

Filling is straightforward: add your liquid into the tube, insert the brush tip, then twist the base clockwise until product advances to the brush. Apply directly where needed and recap after use to keep the tip clean. Avoid overfilling so the brush can seat correctly, and do not force the mechanism by twisting back once fully extended.

• Fill slowly to leave headroom for the brush tip.
• Install brush and rotate base clockwise to prime.
• Cap securely to maintain hygiene and prevent leaks.
• Single-use/disposable design simplifies sanitation.
