Just think of it like a new and improved version of your old rubber bands, Q Knot is a reusable multipurpose tie for just about anything: bundling multiple objects, organizing various cords and much more. Just strap and done. The smart self-locking design makes bundling small objects a piece of cake. Q Knot is made of a stretchable and flexible rubber that will seal plastic bags and breads for freshness better than a bag clip. The non-slip gripping “teeth” design of Q Knot will reinforce the tightness around the bag. Q Knot is also reusable: easy release and retie. Say good bye to the plastic cable ties or your old rubber band.
