Unagi are freshwater eel, and a common sight in Japanese restaurants. They go on sushi, they go on donburi, and they go good plain, too. If you’re new to sushi and afraid of raw things, unagi is the way to go. It’s incredibly tasty.
This, surprisingly, is one of the better covers in terms of actually being able to fit your iPhone in your pocket (don’t wear tight-jeans). It probably only doubles the size of your iPhone. Also brings a new meaning to “is that an eel in your pocket or are you just happy to see me?”
If you’re in Japan and ever get a chance, pop into a place that makes unagi-don. You will feel good afterwards.
