The Massive Cosplay Titan Sword from ThinkGeek is a gargantuan, 5-foot long foam sword with built-in blue LEDs that splits into two pieces for easy transport.
The Foam Titan Sword is over five feet of big bad sword with a whopping 45-inch blade. We designed it to be an awesome costume accessory and the type of thing you can use to chase solicitors off your property. It will arrive in two pieces in a carrying case with a handle. We did this so it would be easy to pack for a convention or anywhere else you want to be respected and feared. Connect the two pieces, click the switch to turn on the blue LEDs, and you’re ready to make a statement on the convention floor, out trick-or-treating, or just chasing away that guy trying to sell you stuff you don’t want.
