ThinkGeek Massive Cosplay Titan Sword
Here is an unboxing of the Massive Cosplay Titan Sword from ThinkGeek.com. The carrying case in the description is actually the box it comes in so save it if you want to use it. It's not for hitting things since its pretty fragile and sensitive, but i find swinging it around is fine (make sure you have room). blue LED lights give it a nice aesthetic. pretty decent size for being 5 feet long. but i wish it were just a tad bigger since i'm almost 6'2, so it looks almost like a normal sword for me, LOL. a quality buy though!
