With an outer diameter of 19.1mm and a total length of 69.9mm, the product boasts balanced, compact proportions. It houses the high-performance JD303 inner mechanism, ensuring smooth opening, closing, and rotation. Crafted from aluminum and finely polished, the square edges feature subtle rounding (radiused corners); this retains the bold, angular aesthetic while ensuring a comfortable grip that feels smooth to the touch. The top cap offers ample space for large-format logo customization, making it an ideal spot for brand identity display.
This product serves as an ideal casing for high-end, iconic lipsticks. Its black-and-gold palette and square profile make it perfect for flagship products or classic shades (such as vintage red). It is also frequently used for premium men's lip care lines, as the square design appeals to unisex or masculine aesthetic preferences.
Issue: Do the edges of the square aluminum cap align perfectly with the base when closed?
Solution: Aligning square tubes is a manufacturing challenge. We ensure perfect flush alignment across all four sides—with tolerances kept within 0.1mm—through rigorous mold precision control and a precisely designed positioning slot in the inner mechanism.
Issue: Is the glossy black finish prone to scratching?
Solution: The surface undergoes an enhanced electrophoresis or anodizing process, achieving "H-grade" hardness. We advise consumers to avoid storing the product directly alongside hard objects like keys.
When stamping a logo, the uneven distribution of force on the square top cap requires a custom support mold to prevent deformation of the tube walls during the stamping process. Store in a dry environment and avoid extreme temperature fluctuations that could cause condensation due to the temperature difference between the interior and exterior of the metal.
