Ever wonder why kangaroos in cartoons are often depicted adorning a pair of boxing gloves? Is it because of the extra spring in their steps that make them such effective pugilists? In any case, this pen that comes with a flashing, functional boxing kangaroo looks set to be a great addition in your stationary collection as you and your mates will be able to hold a slug fest during those slow afternoons at the office. Unfortunately, at $15 a pop, they aren’t exactly the most affordable method to keep yourself entertained.
