Outer diameter of 15mm and a total length of 133.3mm. The tube features a refined matte anodized finish, ensuring uniform color and a non-slip grip. The long, straight-tube design accommodates a longer brush stem, allowing for precise application at the lash roots. Both the cap and tube support customization via screen printing and laser engraving, meeting a wide range of decorative needs—from minimalist to intricate designs.
Primarily used for high-end volumizing or lengthening mascaras and lash-conditioning serums. Its superior light-blocking properties make it an ideal choice for packaging premium nourishing formulas rich in active ingredients.
Issue: Is the extra-long tube prone to air bubbles during filling?
Solution: We recommend a "bottom-up filling" process combined with vacuum extraction to ensure the formula is distributed evenly within the long tube without leaving gaps.
Issue: Does product tend to accumulate at the tube opening?
Solution: This model is compatible with a precision-engineered wiper, which accurately controls the amount of product on the brush and prevents contamination at the opening.
As mascara formulas contain volatile solvents, ensure a tight, seamless seal between the aluminum cap and the tube opening. During storage, it is recommended to keep the product upright to maintain optimal saturation of the brush within the formula.
