This is a straight, cylindrical aluminum tube with an outer diameter of 18.65mm and a length of 72.4mm. A design highlight is the transparent spacer ring embedded in the middle of the tube body; this element cleverly breaks up the visual heaviness of an all-metal design, adding a stylish, airy quality. The surface finish is exceptional, featuring clear, uniform brushing lines. While the side surface cannot be printed on due to manufacturing constraints, the top cap offers an ideal space for stamping and screen printing.
Ideally suited for cosmetics brands that emphasize feminine color palettes and gentle, natural ingredients. Thanks to the serene vibe created by the matte rose gold finish, it is frequently used for packaging lipsticks in "milk tea" or nude-pink shades, as well as high-end lip repair balms.
Issue: Will the transparent spacer ring loosen due to heat?
Solution: We utilize high-strength structural adhesive combined with an interference fit process to ensure the ring remains secure in temperatures ranging from -20°C to 60°C.
Issue: Is it truly impossible to apply graphics to the side?
Solution: As noted, screen printing on the side is not feasible. If a brand has specific requirements, we recommend custom tooling to mold the pattern directly onto the tube wall or using color variations to enhance visual interest.
The brushed finish is directional; during assembly, ensure the grain direction of the upper and lower tube sections is aligned for optimal visual balance. During the filling process, avoid contact between the transparent spacer ring and strong organic solvents (such as alcohol) to prevent cracking of the acrylic material.
