This is the PERFECT glass spray bottle. I use it for homemade cleaners, water to spritz on house plants, and homemade hair spray. I know it's just a bottle but... it's great. I love that it comes with a separate lid for when the spray top isn't in use! I really think the 16oz is a perfect size, too.
I previously had gotten a very similar glass bottle from Grove Collaborative (a wonderful company, other than my problems with their spray bottle) but their bottle's sprayer was really finicky and would stop working randomly. This was is literally the same size bottle, but with a sturdier top!
Tip: when I add liquids to the bottle, I just use a funnel. The bottle's got a pretty small opening and it can be frustrating if you're trying to add a bunch of stuff into the container.
