Tina’s Teeny-Weeny Pack Knife allows you to open pesky plastic packages and boxes with ease. Just extend the blade one click and you can open plastic clamshells without damaging the product inside. The built-in tape cutter allows you to open and break down cardboard boxes without using the blade. When you’re not using it, the built-in magnet allows you to store it on your refrigerator so it’s always within reach. Makes a great stocking stuffer!
