Matfer Bourgeat 1 1/2-inch Flat Boar Bristle Pastry Brush

Manufactured in France, this pastry brush has natural boar hair bristles that are not chemically treated, making it suitable for food contact. Contrary to silicone or synthetic brushes, natural boar bristles retain fluids well thanks to their softness and flexibility, so an egg wash or glaze goes on in an even film.

The handle and collar are sealed, so the head cannot be removed from the handle. That makes the brush resistant to humidity and less likely to breed bacteria, and it keeps bristles from falling out. A hole at the end of the handle lets you hang it. Unlike most natural brushes, it is dishwasher safe. For a wider brush, see the 2-inch flat brush.
