Couple science with a stunning design, and what you’ll have is the perfect bottle for your precious liquid essentials: the 30 ml Glass Roller Applicator Bottle. Whether you put it in your car or in your purse, this travel-friendly bottle keeps your product fresh for ages. The reason behind its power of preservation is two-fold. First, its airtight seal locks in the scent of your essential oil, massage oil, or cologne and blocks out airflow. Second, this bottle is made of ultraviolet glass, which looks and is impressive. What this European-designed glass does is it stops visible rays from damaging your product while selectively allowing beneficial wavelengths to nourish it. With its glass rollerball, you can smoothly apply a blend of freshness to your skin with every use.
