My friend made this homemade pipe(still dont know why he'd do such a thing) and its the crappiest lookin thing ive seen, its a emptied out pen with somekind of metal bolt wrapped by a bandaid(to keep it together) and the metal peice from an earbud to keep the bud from falling through, and the worst part is; he says it hits better than my stealth pipe.
Just ignore his stupid comments and keep cheifing your actually legit piece. Just laugh at him when you see him looking like a crackhead and enjoy the pipe you will no longer let him use because of his ignorance.
