Nice bottles!
I gave homemade natural cleaner to a couple of close friends that liked mine, and used these bottles for that.  None of us has used theirs long enough to know if the sprayers are going to hold up well.  The glass in the bottles is a little lighter in weight than other glass bottles I have, but think they will hold up ok.  The cobalt blue color is pretty.  I would tentatively recommend these bottles, and would recommend that others give them a trial run as I have.  At this point, I would say I will order again.
