Review (5/5): Great quality for the price
Bought these for making cleaners with essential oils and love them! The cobalt blue is supposed to help "avoid deterioration and protect the aromatic and therapeutic properties" of the essential oils; either way, it's fine by me because they look beautiful. The spray bottle lids screw on tightly, the spray stream is consistent, and they're thick glass so they're very sturdy. Also a good price!
