Indeed it is Ninja. And if you want to go to the next step, a magnetic screw tray is even more awesome.

I picked up one of these at the county fair for 5 bucks. As you're taking the screws out of your blaster, you simply line them up  relative to where they belong and voilà, they stay there until you're ready to reassemble. Low tech, reusable, and super reliable. Love it !
