Glue doesn't always have to be applied directly from the bottle; depending on the project and surfaces, sometimes using other tools is better, depending on your goal. Generally, you'll want to use disposable tools that can be thrown away after use since glue can damage the tool or brush. We recommend the following tools for applying glue: sea sponges, cosmetic sponges, toothpicks, inexpensive bristle brushes/paintbrushes, foam brushes, cotton swabs.
