Cooling Metal Roller Ball Applicator Tube 15ml PE Squeeze Body Leak Proof Travel Size for Under Eye Serum Packaging

This 15ml metal roller ball applicator tube combines a stainless steel roller with a soft PE squeeze body to deliver serum and gel formulas with a cooling touch. The metal ball rotates freely in its housing and releases product only while it is moving across the skin, which gives the user a controlled film instead of an uncontrolled surge. A 19mm flat oval body fits a pocket or a travel kit, and the tight-threaded cap with a sealing ring keeps the ball chamber closed between applications. The pack is built for under eye serum, cuticle oil, scalp tonic and lip gloss, and it accepts silk screen printing, hot stamping and matte lamination on the body so that a premium look can be produced at a moderate unit cost.

• Stainless Steel Roller Ball: a polished 15.8mm ball spreads product evenly and transfers a natural cooling sensation, which is valued in depuffing eye serum and soothing gel formats.
• Soft PE Squeeze Body: the 15ml barrel compresses with light finger pressure, so the user controls flow rate without a pump mechanism or an airless piston.
• Leak Proof Sealing Ring: the cap carries a moulded ring that presses against the ball housing, preventing seepage in a bag or during air freight.
• Flat Oval Travel Format: the 19mm oval profile resists rolling on a counter, fits a 100ml security bag with room to spare, and reduces carton cube for export.
• Multi-technique Decoration: bodies accept silk screen printing, hot stamping in gold or silver, and soft touch matte lamination for a premium shelf presence.
• Refill and Reuse Friendly: the ball housing unscrews from the body, so brands can offer a refill cartridge programme without changing the applicator head.

Eye care is the primary use case. Under eye serum, caffeine gel, peptide concentrate and depuffing roll-on all benefit from the metal ball, because the applicator massages the orbital area while it deposits a thin layer, and the cooling effect is felt immediately without refrigeration. The 15ml fill supports a thirty day routine at two applications per day, which matches the claim cycle most brands use for eye products.

Beyond eye care, the same tube serves cuticle oil, nail serum, lip gloss, lip oil, scalp tonic for targeted hair care, and spot treatment gel for acne care. Because the ball dispenses only during movement, a viscous gel and a light oil can share the same platform, which lets a brand build a small family of roll-on products on one mould and one decoration process.

Units are packed with the ball housing fitted and the cap torqued, 2,000 pieces per export carton, in a polybag with a desiccant sachet for humid routes. Ball retention force and cap removal torque are checked each shift, and every batch passes an air pressure leak test before packing. Filling support can be quoted in house, including ball insertion, serum filling and capping on a single line.

Samples of the stock format are free, with freight at buyer cost, and decorated samples follow artwork approval within seven working days. Customisation covers body colour matching, ball diameter alternatives, cap shape, print layout for the printable area, and retail carton design. Mould development for a new oval profile or a larger 20ml version takes 25 to 30 days after drawing sign off, and the tooling remains dedicated to the buyer for the life of the project.
