Beyblade

It's amazing that because of an anime cartoon series they can get away charging $20 for a plastic and cast zinc alloy disks. top that from the very same factories produced nearly the same thing 30 years ago that sold for for a few cents.

Some of these metallic disks sell for as much as $40 or more.
Such as a : TAKARA MG Bakuten Shoot Beyblade 爆転シュート ベイブレード Magne Weight Disc (A-87)

Kids there ain't nothing new here other then a way to waist your parents money.
