Just when you thought it couldn’t get more scientific, the age of “Advanced Perconomics” hits. From the amazing brain of Micah Evans, Grav Labs has paired up to produce the future of bong technology with the one of a kind “Upline” collection. Crafted with the brand’s signature glass quality, this 12-inch design draws your eye to the spine-like stack of percs where all the magic happens. The water pipe combines the scientific power of hydrodynamics, gravity diffusion, and directional airflow for cleansing bubbles galore. All with the famous “Upline battle cry” when cleared! The arched neckline makes it a comfortable, natural-feeling draw with the organic luxury of soothing water. It’s a pipe-making masterpiece where engineering meets artistic inspiration. You can take it to the next level with customized attachments for a second station of Grav Labs and/or Upline engineering (sold separately). It’s an Upline x Grav Labs dream come true!
