I'm a dude that is 5'9, pretty lean/thin build so I bought a size M thinking it'd be fine. Considering that when it comes to Western sizes an M would be a little large on me but still fit just enough I went with it. I like the material and fit in general, but just barely. I'm kind of afraid to wash and dry it now considering the fact that it might shrink to an un-wearable size. My advice, always buy a size up when it comes to Eastern measurements.

A little bit of a mishap with the delivery (was not home at the time to sign for it), but eventually it showed up at my door again a few weeks later and I'm glad it did.
It's a tight fit around my phone which I love and the material seems pretty durable.
The only things I'm concerned about are, the metal NERV plate seems like it'll fall of eventually, and two I just wish the magnet holding the case together was a little stronger but that's just me.
Overall a really good buy.

As stated above the build quality is very well done, my only gripe with it is that it turned out bigger than I had expected so it's kind of awkward in the pocket.

Other than there being a small dent on the wooden box (hardly noticeable by the way), everything is fantastic. The pieces, the presentation the packaging, all superb.
This being my first delivery from TOM I'm highly impressed and pleased.
