When you have a can with liquids in them that need to be strained out, some people have very interesting ideas to do this. Most are relatively complicated, so why not simplify your life by using the Can Colander. This item fits into the standard three inch cans to strain liquids not needed. Great for tuna, pet food, and more. As an accessory to this item, there are two plastic hooks made to pop open the tabs of the cans.
