10 ml Clear Glass Roll-On Bottle with Black Cap & Plastic Rollerball

How to Use

Fill the bottle with your essential oil blend, perfume, or serum, leaving a small amount of headspace at the top so the roller insert can seat properly. Place the roll-on insert over the neck and press down firmly until it snaps into place. For the easiest, most secure fit, we recommend using our roll-on insert press/removal tool, which applies even pressure across the housing and helps prevent damage to the ball or collar. After inserting, screw the cap on tightly. This final step can gently press the insert fully into place if it’s sitting slightly proud of the neck, helping create a snug, leak-resistant seal.

Before first use, tip the bottle upside down or give it a gentle shake to saturate the roller. When refilling or changing formulas, use the removal side of the tool to lift the insert straight out rather than prying it by hand. This protects the bottle neck, keeps the fitment intact for reuse, and makes filling faster and cleaner, especially when working with multiple bottles.

Compatibility & Testing

Roll-on bottles perform best with low to medium viscosity liquids such as essential oil blends, perfumes, and lightweight serums. Very thin, alcohol-heavy formulas may dispense more quickly or seep, while thicker oils or gels may restrict flow or prevent smooth rolling. For this reason, we always recommend testing your specific formulation and fill process for flow, fit, and leak resistance before scaling up production.

Packaging performance can vary depending on viscosity, solvents, and fragrance components, so small batch compatibility testing helps ensure the best results for your finished product.
