Review (4/5): Good bottles, mediocre sprayer
These are very nice blue glass bottles. They came in good shape with no chips or scratches. Also, these are blue glass, they're not painted.
The sprayers aren't great. I mean, they work fairly well, but I don't think they are going to last very long with regular use. Fortunately, sprayers are easily and cheaply replaced.
The chalk labels are a nice addition, the funnels are a bit pointless. They're very small, and the size of the bottle necks don't require such a small funnel. Still, I've made good use of them with some of my smaller bottles I use.
