Nothing says on the go like a pipe you can wear around your neck. The GRAV Mini Spoon has a donut mouthpiece that can be threaded with a string or chain. This donut also catches ash and cools smoke. It doesn't get more portable or discreet than the Mini Spoon, but this piece still holds more flower than most one hitters and chillums. No matter where you take the Mini Spoon, it will get you where you need to go.
