Improvements 2-pack Safe Bristle Brush Blade Cleaners Improvements come up with a clever way to safely hand wash your kitchen knives... and more. The secret is a hard plastic U-shaped exterior with textured grip and two sets of bristles inside. Simply draw your knife—or silverware, or edge of a dish or pan (where all the burnt on sticky stuff is)—the bristles contact both sides at once, and the hard plastic shell helps keep your hand away from any sharp edges. So clever. So simple. So useful. You'll wonder how you ever did without it!    What You Get (2) Cleaning brushes (2) Use & care guides
