31.5mm Tamper-Evident Ribbed Black PP Screw Cap with Violet Inlay

What this packaging is

Designed to pair exclusively with Miron's Castor and Pollux violet glass bottles, this 31.5mm Tamper-Evident Ribbed Black PP Screw Cap with Violet Inlay brings a finished, coordinated look to premium oil and tincture packaging. The ribbed exterior improves grip, while the tamper-evident band delivers the consumer confidence that body oil, CBD oil, essential oil, and herbal tincture brands need at retail. Built on a 31.5 STD thread with tight tolerances at 35mm diameter and 22.5mm height, the fit is clean and consistent. Manufactured in Europe from durable polypropylene, this closure is available with stock availability for smaller orders, making it easy to test or restock quickly.

Why brands choose this

• Built-in tamper evidence for regulated product categories: Oils, tinctures, CBD, and herbal extracts often face retail and regulatory pressure to show tamper evidence at point of sale. This cap delivers that assurance directly, without requiring brands to source a secondary seal or add a shrink band.
• Engineered fit for Miron Castor and Pollux bottles: The 31.5 STD thread is calibrated specifically for Miron's violet glass bottle range, so brands building a lineup around Miron packaging can count on consistent, leak-free compatibility across SKUs rather than troubleshooting thread tolerances.
• The ribbed grip supports the wellness ritual at point of use: In body oil, massage oil, and bath oil categories, consumers open packaging repeatedly and often with wet or oiled hands. The ribbed sidewall makes one-handed opening easy, reducing friction in the use moment and reinforcing a considered, premium product experience.
