Outer diameter of 18.75mm and total length of 72.8mm. Crafted from highly ductile aluminum, the cap ensures the double-line pattern is formed with crisp, uniform precision. It is compatible with the industry-standard JD303 (16.5mm) inner mechanism, ensuring high assembly yields and excellent durability. The top cap supports both screen printing and stamping, allowing brand details to blend seamlessly with the luxurious rose gold finish.
This product is an ideal container for premium holiday gifts and lipstick collections targeting a sophisticated, elegant demographic. Its unique double-line design ensures it catches the eye more effectively than standard glossy tubes when displayed on retail counters. It is perfectly suited for packaging velvet matte lipsticks or haute couture color ranges, effectively conveying a brand ethos of "refined living."
Issue: Will dirt accumulate in the cap's grooves?
Solution: The double-line grooves are designed with an optimal depth, and the surface features a smooth electroplated finish, making it highly resistant to dirt buildup. Daily cleaning is quick and easy.
Issue: Can the logo on the top cap be printed in color?
Solution: Yes. The glossy rose gold background is ideal for multi-color screen printing—particularly white or dark brown—creating excellent color balance.
Due to the decorative lines on the cap, soft silicone grippers must be used during the automated filling process to prevent mechanical grippers from damaging the pattern's surface integrity. Storage requires a constant temperature to prevent micro-cracks in the electroplated layer caused by thermal expansion and contraction.
