Beyblade X BX-00 Cobalt Dragoon 2-60C Metal Coat: Black Set of 2 Brand New, Unopened, Beyblade Code Unused
I've carefully selected two heavier blades.
Since they're unopened, I don't know the exact weight of the blades, but the box itself is heavy, so there's a high probability they contain heavy blades.
While the usual weight is in the 178g range, this product weighs in the 179g range.
