This is a PVC, soft-vinyl, or other plastic figure kit with pre-painted parts.
Here are five adorably cute little "One Piece" figures--stick 'em on your fingers and they make great finger puppets! Included are Luffy, Ace, Mihawk, Crocodile, and Edward Newgate. Each is about 4cm tall. Please note that the photos shown are of a prototype; the production version may vary. Also, figures such as this are mass produced and as a result some inconsistencies in finish and painting may occur; these are not considered manufacturer's defects. If you absolutely must have perfection, prepare to do some touch-up work on your own.
