45-400 Black Grooved Black Tinplate Screw Cap with Violet Inlay

What this packaging is

A grooved tinplate screw cap with a striking violet inlay, this 45-400 closure is purpose-built to pair with Miron glass bottles and their signature light-filtering properties. The 45/400 neck finish delivers a secure, reliable seal across natural cosmetics, skincare, perfumes, and supplement applications. At 44.8 mm in diameter and 11.6 mm in height, the cap sits proportionally on standard Andes-compatible bottles. Manufactured in Europe, it reflects the material precision and finishing quality that brand teams expect from that supply base. Stock availability supports smaller order quantities for brands testing formats or launching limited runs.

Why brands choose this

• Engineered to pair with Miron light-filtering glass: This cap is specifically designed to complement Miron glass containers, which block visible light to protect light-sensitive formulations — making it a functionally coherent choice for natural skincare, botanicals, and supplement brands where ingredient preservation is a selling point.
• Grooved tinplate construction signals premium, tactile quality: The ribbed tinplate body provides a confident grip and a satisfying, weighted feel at point of use — a sensory cue that elevates perceived product value for wellness and apothecary-positioned brands without requiring additional decoration.
• Stock availability keeps development timelines flexible: With stock available for smaller orders, brand teams can move efficiently through sampling, formulation testing, and limited-edition launches without committing to large production runs upfront — a practical advantage when validating new SKUs.
