Best Idea Since the Vaporizer in the early 60's
Simple. Inexpensive. Elegant. Instead of putting the joint in a holder, put the holder IN the joint. Beyond genius. 7mm is the perfect size for 89mm rolling machines. Why didn't anyone think of this fifty years ago? Probably because everyone was STONED. Keep up the good work girls and boys, this product hit the ball right out of the park.
