If you love bringing your favorite essential oil wherever you go, then you have to store it in a bottle that protects it from spills and degradation from sunlight and air. The 10 ml Stainless Steel Roller Applicator Bottle does that and more. Rather than a flimsy plastic rollerball, this bottle comes with a rust-resistant, sturdy stainless steel rollerball, which won’t melt or wear away when exposed to your potent oil. Its airtight cap prevents your blend from spilling all over your bag and stops air from entering and ruining it. But this bottle isn’t your normal glassware—it’s made of lab-tested ultraviolet glass. Designed in Europe, this glass keeps out damaging visible light and permits beneficial rays to rejuvenate your product. In other words, it preserves your blend’s potency—even as you travel—for years more! What's Included? 10 10 ml Stainless Steel Roller Bottles with BPA-Free Plastic Caps
