Gundam Epyon with Bean Sword

Listening to: Nothing.

I was surfing eBay to find listings on things that I could sell when I came across this listing for a Gundam Wing Epyon. It was in mint condition and included both the Heat Rod and the Bean Sword.

I was pretty sure they meant Beam Sword, but realized that Bean Sword actually makes a lot more sense.

What the aitch is a Beam Sword? Seriously.
