Now you can be just like Yugi with your own Millennium Puzzle! Japan is coming out with gold Puzzle pendant to wear around your neck. It comes with a 2ft long chain, but the actual pendant itself weighs only 23 grams & is quite small. Like, the size of a quarter, so don't expect it to look exactly like Yugi's. But it's still made out of gold, & as a result is quite expensive. Retail price is 13,650 yen (~$140). It doesn't come out until October though, so you got plenty of time to save up. So if you want one that badly, you can reserve one for yourself right here:
