The Upline Taster by Grav Labs is their most compact piece. At just 3 inches long it is a perfect little one hitter giving a great hit every time you load it up. Made of sturdy 2.5mm glass it has one restriction at the base of the bowl to contain your herb and the three more restrictions near the mouthpiece to aid cooling of your smoke before you inhale.
