The Rhino Coffee Gear 58.5mm flat tamper is a 'handle-less' tamper making it easier on the wrists. Designed with a two step locking system, it is easily adjustable to allow the user to set and tamp to the desired depth every time.
Adjusting the depth:
Loosen the top section by turning to the left (counter-clockwise).
Use the bottom black adjustment ring to set the desired depth.
Tighten the top section back down until tight by turning to the right (clockwise).
