CollectionPrinny: Can I Really be the Hero? Mascot Strap Set Vol. 2
Game Title: Prinny: Can I Really be the Hero?
Released As: Commercially available straps
Manufacturer: Toy's Planning
This Prinny strap set features one PVC strap, and a set of three interchangeable metal mascot charms, so you can pick and choose which charm (or charms) you want on the strap.
Although this set is made for Prinny: CIRbtH?, it was released in late December 2010 - some months after Prinny 2 had been released in Japan. The set expands upon the vol. 1 set of straps, which had been released earlier that year.
These were originally available from several Japanese online stores.
