Empty Glass Spray Bottle - 16 oz.
There's not a lot that needs to be said about something this simple. It's an empty GLASS spray bottle. You can replace countless plastic bottles with a single glass bottle. Use it in alongside your All-Purpose Home Cleaner in a second bathroom, or for any DIY recipe you might have (we're looking at you, vinegar and water people!).
Write on the glass with a permanent marker its contents, or add a label, to clearly communicate what's inside.
