28/400 CT Gold Gold Metal Continuous Thread Caps

This packaging closure pairs a defined specification with practical manufacturing and consumer-use considerations. The 28/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Potential uses include cosmetics, personal care, wellness, supplements, household, and specialty products. Prototype with the intended container and product to verify torque range, sealing, and consumer handling. The objective is a package that feels intentional at every point of use.
