These holders/stands allow you to keep your bottles so they're ready to be used when you need them. Works great for most squeeze bottles - 3-In-1, Aleene's, Art Institute Glitter Glue, Beacon, Nuvo, etc. They are created on a 3D printer from PLA plastic so some imperfections are expected that do not impact the function. We're offering them in various colors to mix and match as you wish.
