Review (5/5): These bottles are a great option for use with essential oils!
These 4 oz. cobalt glass spray bottles are perfect for mixing essential oil room sprays. The mist from the sprayer is very fine. The reusable, black chalkboard labels provided are perfect. I opted to write on one of the labels with a white gel pen and it worked great, although this makes the writing permanent. I will be using the remaining bottles for essential oil room sprays to give as gifts. My order arrived quickly and undamaged.
