This set contains 12 accessories for a deadly ninja assassin. They currently fit Lego hands, but you can trim them to fit Minimate hands. All you need to do is shave a sliver of plastic off each side of the handle with a hobby knife. All of the photos of the Minimate above show these weapons after trimming. You will need to trim them yourself, but it is a quick and easy process. This set is made of ABS plastic, the same plastic that Legos are made of.
