>>1221971im not trolling. i got the idea while eating fried fish and eating the fins which have spines in them which are usually inedible, but the fish was fried long enough that the spines which are made of calcium were crunchy and brittle. it was like a fish chip. i figured nails are thin and also made of calcium, so it should work just as well. and i was right. if you're not an extreme foot fetishists then obviously this isnt for you, but for those of us that love feet and all feet-related things, this is the next logical step.
