This model features an outer diameter of 18.7mm and a slender, symmetrical double-ended design. The tube surface boasts a highly saturated, glossy magenta finish with a translucent quality and a smooth tactile feel. Its most distinctive feature is the pair of narrow silver rings in the center; these not only serve to visually separate the two ends but also provide a visual guide during rotation. The flat top caps offer ample surface area, fully accommodating complex screen printing or intricate logo stamping to ensure the brand identity is rendered with exceptional clarity on the metal substrate.
This product is primarily suited for professional-grade cosmetics or dual-action care lines—such as "daytime moisturizing + nighttime repair" lip balms or "matte lipstick + clear lip glaze" combinations. Its elongated shape also makes it an excellent choice for eyeshadow sticks or multi-functional concealer sticks; the extended length allows for a wider range of motion, facilitating precise application by makeup artists.
Issue: How is the coaxial alignment of the double-ended structure ensured?
Solution: We employ a high-precision aluminum drawing process during production to keep the concentricity deviation between the two tube ends within a minimal range. Specialized positioning fixtures are used during assembly to ensure a consistent feel when opening and closing both ends.
Issue: Will the silver rings oxidize or discolor? Solution: The silver ring also undergoes an anti-oxidation anodizing treatment, offering exceptional chemical stability and long-term resistance to corrosion from fingerprint oils and atmospheric elements.
Due to the product's length (116.35 mm), special care must be taken during packaging and transport to prevent the middle section of the tube body from bending under pressure; using a compartmentalized EPE (expanded polyethylene) foam insert for stabilization is recommended. Horizontal filling or a specialized vertical filling line should be used to ensure that the fill height and weight of the product at both ends remain perfectly balanced.
