DupakSYS 3ml Nail Oil Pens 100-Pack — Clear Refillable Brush-Tip Twist Applicators for Cuticles & Serums

DupakSYS 3ml Nail Oil Pen is a set of 100 reusable brush-tip twist pens designed to dispense thin or viscous liquids precisely for cuticles, lips, lashes, and small cosmetic tasks.

These clear twist pens hold about 3 milliliters each and come with soft brush applicators and labeling stickers, providing a tidy, portable way to carry oils, serums, lip glosses, or cosmetic samples. The pens are made from clear, food-safe polypropylene and are lightweight for travel or professional use. They’re intended for non-corrosive, non-acidic liquids and are disposable after use.

How do I fill and use a DupakSYS nail oil pen?

Filling is straightforward: add liquid to the reservoir, seat the brush tip, then twist the base clockwise until product reaches the brush. Apply as needed and keep the cap on to avoid leaks. Avoid overfilling and do not force the twist mechanism past its stop.

• Fill gently — leave space so the brush can press in without overflow.
• Insert brush tip fully and twist clockwise to feed liquid.
• Replace cap after each use to keep contents hygienic and leak-free.
• Not suitable for strong acids, alkaline solutions, or high-alcohol formulas.

Are these pens leak-proof and travel-friendly?

Each pen features a sealed brush cap and a twist-feed body to limit accidental spills, and the slim dimensions make them easy to slip into a purse or kit. Because they are lightweight and compact, they’re ideal for on-the-go touch-ups or for carrying multiple formulations without bulk.

• Sealed brush-top prevents drips during transport.
• Approx. 3ml capacity fits airline-friendly personal use amounts.
• Slim 4.96-inch length tucks into cosmetic bags or pockets.
• Use included stickers to label different formulations for travel.

What liquids can I store in these empty brush pens?

The pens accept a wide range of thin to moderately viscous cosmetic liquids, such as nail oils, lip gloss, serums, or light creams. They are not intended for corrosive, strongly alkaline, or very high-alcohol solutions that could degrade components or cause leakage.

• Suitable: cuticle oil, lip gloss, eyelash serums, facial serums, light foundations.
• Also useful for: teeth-whitening gels, spot treatments, or small paint details.
• Avoid: strong acids, alkaline cleaners, and high-percentage alcohols.
• Disposable design — recommended single-use for hygiene or short-term refill.
