Have potent substances at home? Time to keep them secure from kids and protected against harmful elements. We offer a bottle that combines science with style: the 15 ml Child Proof Graduated Pipette Dropper Bottle. At first glance, this travel-friendly bottle seems to sport a premium kind of glass. But the reason behind its dark purple glass is that it’s lab-designed with ultraviolet technology. It prevents harmful light from entering while allowing beneficial rays to nourish whatever’s inside. Add that to its airtight seal and glass graduated pipette, and you can enjoy precise drops of longer-lasting tinctures, essential oils, or medicinal syrup! Plus, kids can’t tamper with this bottle—it comes with a childproof cap that needs to be pushed down and twisted to open. • airtight, smell-proof, & light-filtering: world's best ultraviolet glass jar with bpa-free plastic lid. • the perfect size and shape: a versatile container—great for herbs, spices, and cosmetics.
