uadbau 6 Pcs 3ml Empty Cuticle Oil Pen with 4 Pcs Transfer

These are 6 transparent 3ml twist-action cuticle oil pens from uadbau, supplied with 4 transfer pipettes and soft brush tips for precise, leak-resistant application of nail oil, lip gloss, serums and more.

Compact and disposable, the uadbau oil pens are made from clear, food-safe PP to let you see product levels at a glance. Each pen features a sealed brush tip and a simple clockwise twist mechanism that pushes liquid out evenly for controlled spot application. The set also includes four pipettes for easy, mess-free filling, making these pens useful for salon touch-ups, travel kits, or DIY cosmetics and nail-care formulations.

How do these pens prevent leaks and stay travel-ready?

The pens use a sealed brush-top design and a twist-dispense mechanism that reduces spills and accidental output. Their slim, 5.3 x 0.51 inch profile fits into pockets and small bags without adding bulk.

• Sealed white brush cap minimizes drips when stored upright or sideways
• Twist-to-dispense avoids sudden gushes common with pumps
• Compact 3ml size meets most travel and handbag needs
• Durable PP plastic resists cracking under normal use

What liquids can I safely store and apply with these pens?

These transparent pens are suitable for a wide range of low-acid, low-alcohol liquids such as cuticle oil, jojoba or other carrier oils, eyelash serums, lip gloss, and many cosmetic serums. Avoid high-acid or high-alcohol substances that can degrade the internal plastic or seals.

• Ideal: oils, lipid-based serums, clear lip gloss, nail and cuticle formulations
• Not recommended: strong solvents, high-acid formulations, pure alcohols
• Single-use design reduces cross-contamination risk for sensitive products
• Clear body helps track remaining product and batch labeling

How do I fill and operate the twist pens without leaking or breaking them?

Use one of the included transfer pipettes to place liquid into the pen body without overfilling. After attaching the brush tip, turn the twist mechanism clockwise until a small amount appears on the bristles, then apply as needed. Do not twist backward, which may damage the internal gear.

• Use pipette to add fluid slowly; leave space for brush tip insertion
• Attach brush tip securely before first twist
• Turn only clockwise to advance liquid toward the brush
• Cap after use and discard per single-use guidance

How should I store and maintain these pens for best results?

Cap pens after every use and store them upright when possible to keep the brush tip from drying out or collecting debris. Because these pens are intended as disposable applicators, avoid refilling with aggressive chemicals and replace when the brush shows wear or contamination.

• Keep capped and stored upright to protect the brush tip
• Replace pens if bristles fray or fluid leaks appear
• Do not attempt to disassemble or reverse the twist mechanism
• Dispose responsibly according to local regulations—PP plastic

Who this is for: The uadbau 3ml twist pens suit nail technicians, beauty professionals, and individual users who want precise, portable dosing for oils and serums. They are useful for travel, salon touch-ups, sample distribution, cosmetic DIYers, and anyone who prefers a clean, controlled brush application without bulkier dispensers.
