From the highest quality performance Aircraft Grade Aluminum! Awh nevermind thats just a plain lie... it is aluminum though. And it does fit between the lower case and the faceplate of an Xbox perfect. Way better than a screw driver or anything of narrow width, it applies even pressure across the whole clamping mechanism. In the end its just a hunk of aluminum you could get elswhere but if you get it here you know it will arrive fast and fit perfect! (electrical tape handle and sharpie writing not included ;-)
