Hey so the work that goes into making a realistic mask is actually very complex meaning Kuroha needs access to (probably) Silicon because latex wasn't a thing until the 1900s oh yeah and most realistic masks are molded off a clay sculpture of a face meaning she either goes around making casts of random peoples faces or is some savant when it comes to sculpting
on top of that making the mask look actual realistic would take heavy paint work to making things like skin look real and y/know alive (meaning she probably has a collection of some kind of paints and makeups to do the job) and the hair would need to be sewn into it single strand at the time for realism's sake
so basically what im saying is Kuroha utilizes several skills to make these masks, skills that could profitable on their own but she just decides to use them to get a magic pair of shoes (and fails in doing so)
