This brush features non-stick silicone bristles that are easy to wash with water, and quickly shed dried glue for long-lasting service. They’re also spaced to hold plenty of wet glue, meaning less time dipping and more time spreading. Use the narrow dimension for edges and the wide dimension for faces. The comb paddle end opposite the bristles can be used like a pen for finer detail work such as mortise and tenon, dovetail, and box joints, or like a spatula for spreading glue into grooves and mortises.
