I think i see what your talking about, and yes they are like that.
The reason is if it was bent slightly to match the curve of the phone perfect, you wouldn't be able to put it in either way. What i mean is the curve it would need would make the pen have to be exactly placed, instead of being able to fit either way. (As long as pointy end goes first lol)
