Why brands choose this

• Purpose-built for Miron jar compatibility: At exactly 36.4mm, this disc is sized to work with Miron violet glass jars, removing the guesswork for brands building packaging systems around light-protective glass and reducing component sourcing friction.
• European manufacturing with ISO-certified consistency: Produced in Europe under ISO-certified processes, each disc delivers repeatable seal performance across production runs, a meaningful quality signal for brands in regulated categories like supplements, naturals, and prestige skincare.
• Black finish supports premium unboxing experience: The black interior liner creates a polished, intentional look when the jar is opened, reinforcing the premium positioning that brands in high-end skincare, fragrance, and wellness expect from every touchpoint, including the ones consumers see up close.
