This colorful set of three Monet Moonlight aluminum & glass spray atomizer bottles will let you be creative with your essential oil DIY projects. Mix up a germ blend to carry in your purse or a pillow spray to keep by your bedside. Or maybe you just want to mix up some of your favorite essential oils to create a personal fragrance. The compact 6ml / 0.2oz bottles are refillable and you will be able to use them over and over again. These bottles are beautiful brushed aluminum on the outside and glass on the inside. Unscrew the spray head to fill or refill the glass bottle. In a spray bottle or atomizer, you should always use an essential oil blend recipe that is 10% or less essential oil. Full strength oils will damage the spray mechanisms. There are many good recipes online for personal fragrances, room sprays, pillow sprays, germ blends and other therapeutic blends that will work great in these spray bottles.
