This glue holder is designed to fit the Tombow Multi Liquid Glue (52190 and 62191 - not included), and the larger Tombow Aqua Liquid Glue (52180 - not included). These holders allow you to keep your glue upright so they're ready to be used when you need them. They are created on a 3D printer from PLA plastic so some imperfections are expected that do not impact the function. We're offering these in various colors so mix and match as you wish.
