Review (5/5): Glass spray bottles.
These spray bottles are glass, instead of the rather more usual plastic that you will find. So, if you're looking for glass, these should suit your needs. However, I found that the included spray nozzles would not "hold in one position," no matter how tightly I tried to screw them down onto the bottles. This may or may not matter to you, and of course you can always try other nozzles you might have available.
