5 different characters billed as being from Sonic X, though Big wasn't in it a whole lot. These are really small, but the sculpts are pretty good, except for Knuckles who's head clearly suffers. For some reason the mini-big seems cuter than expected.
These are all made of semi-hard plastic, and are from Japan. There for, it's likely that they are capsule figures of some sort. The figures say "TM©2000SEGA China"
