They’re thicc and they’re chunky and that’s how we like ‘em. These Red Eye Glass® chunky 7mm & 9mm bubble base tubes are exactly what the doctor ordered. We’re not sure if this doctor is licensed or not but we’re a fan. With extra thick mouthpieces and female ground joints, these bongs are ready to rumble! Available in 3 size, 2 thicknesses and clear and colour changing.
