Tiger Tacos

Anyone who has ever opened or packed a typical cardboard box knows the challenges of getting the flaps under control. Tiger Tacos ($19/4-pack) are simple metal taco shell-shaped helpers that go on the top of a folded flap, keeping it in check and out of your way. If you think metal might be a little too heavy duty for your needs, you can get a 4-pack of plastic Tiger Tacos for just $5.
