It comes in a small glass bottle. I believe all their concentrates come that way since they are focused on reducing plastic consumption.
Any one have an idea on how to get the label off? After I cleanse it, I believe it will work well for spell bottles.
I agree with @Ostara that’s basically how I do it too, except I use lemon oil to dissolve the glue. Any citrus oil should work though. I think they are making the glue stronger than it use to be because when I soak them, the paper dissolves leaving the glue. It comes off with a little scrubbing though.
