This model features a well-proportioned design with an outer diameter of 18.8mm and a total length of 69.4mm. It boasts excellent mechanical performance, accommodating the standard 16.5mm JD303 inner mechanism to ensure a smooth, consistent rotational feel. The aluminum casing undergoes multiple polishing stages and supports customized logo application via screen printing or precision stamping, allowing the brand identity to stand out against the black background.
Widely used in flagship color cosmetic lines. Its minimalist black appearance complements a full spectrum of lipstick shades, ranging from nudes to classic reds. It is also a preferred choice for professional stylist lines, men's lip care products, and business-style cosmetics, reflecting a brand image of sophistication and stability.
Issue: Does the glossy black finish easily show fingerprints?
Solution: The aluminum surface features an anti-static, oil-resistant coating. Should fingerprints appear during use, simply wipe gently with a soft cloth to restore its pristine appearance.
Issue: How is the fit tightness of the inner mechanism ensured?
Solution: This model is specifically designed for the 16.5mm JD303 mechanism with strict tolerance controls. We recommend using fully automated press-fitting equipment to ensure a perfect fit between the inner mechanism and the inner wall of the aluminum tube.
As aluminum conducts heat rapidly, care should be taken to store the product away from direct sunlight during high-temperature summer transport to prevent uneven heating of the internal formula. Regarding custom color matching: due to the nature of the anodizing process, slight variations in the depth of the black finish may occur between batches; we recommend finalizing a color standard before mass production.
