This is not the first time we find a foldable waterproof keyboard, but this is the first time we see a keyboard with such special arrangement of keys. Unfortunately, we don’t have a bigger picture so we cannot see the keys clearly, but the top three lines must be related with the F function key zone and multimedia key zone.
The most interesting thing is that the Enter key is super huge but the Space is extremely small (if you can see where it is), and the edit keys and direction keys are also have unique arrangement. The Enter key and + key at right might be wired shape because they need to fit the shape of the whole keyboard.
