The thin tips reach into tight spaces to spread glue evenly on all mating surfaces. Unlike brushes, they won't shed bristles, and they hold just enough glue for a thin coating without excessive squeeze-out. They are also handy for any other detail gluing application. The first two paddles have four tip widths: 1/8", 1/4", 3/8" and 1/2". The third paddle has two 1/2" ends: one offset like a spatula, and one with an angled end.
