Topic says it all.
A box of generic styled european monks with swords. If using the standard composition of 28mm (body+legs, arms, head) such a kit is just a simple arm+head swap away from being easily kitbashable into virtually any setting/genre/period.
The plastic 28mm scene really has no robed figures that would be servicable as historical clergy taking up arms despite such a kit being probably more versatile than anything else on the market.
Im certain that such a kit would be profittable just because of how many gamers would be able to fit it into one project or another.
