Some of the V-Force (MG) Beyblades that use the magnetic spin gear core may have slight cosmetic wear to them being over a decade old the metal surface plating of the core may have degraded (delaminated) off, but is covered by the outer spin gear so you don't really see it. Slight tarnishing may have occurred to the weight disks, spin gears and other metal parts. Metal polish can be used to bring back the shine.
These Beyblades being over a decade old you may find that the decal stickers might have little tack to them and have dried out a little, simply just use a thin layer of stick glue to increase the adhesive on the sticker decals.
