Includes power supply, 13pin cable (from pickup to synth) and instrument cable (from synth to amp) as well as the "case".
I mounted pickups on my guitar with screws. I would recommend 2 sided tape unless you like screw holes in your guitar.
If you're unfamiliar with this unit, check out some YouTube vids.
