3.4oz / 100ml 20-410 Miron Glass Square Cosmetic Bottle

What this packaging is

Miron's proprietary violet glass does something ordinary glass can't: it selectively filters sunlight, blocking the wavelengths that degrade sensitive formulations while allowing beneficial light through. The result is extended shelf life, preserved aroma, and maintained color and texture — without added preservatives. This 3.4 oz / 100 ml square cosmetic bottle features a 20-410 neck finish for broad closure compatibility and a geometric silhouette that commands shelf presence. Produced in Europe, it's well-suited for fragrance, hair oil, body oil, face toner, and perfume. For brands building around clean, natural, or potency-forward positioning, this bottle is a packaging statement in itself.

Why brands choose this

• Built-in preservation without preservatives: Miron's proprietary violet glass filters out harmful light wavelengths while allowing beneficial ones through — protecting potency, aroma, and texture over time. For brands formulating without synthetic preservatives, this is a structural advantage built into the packaging itself.
• Square silhouette creates ownable shelf presence: The geometric, flat-sided profile stands apart from the round bottles that dominate fragrance and facial oil shelves. That distinction matters at retail and in DTC flat-lays — the shape communicates intentionality and premium positioning before the consumer reads a word of copy.
• Versatile 20-410 neck opens closure options: The standard 20-410 finish works with a wide range of closures — pumps, droppers, sprayers, and caps — giving brand teams the flexibility to adapt the same bottle to different product formats or ranges without sourcing a new component.
