The Elev8 bottle opener dab rig with a 20 tree perc is unreal. Our team of foreign artisans really did an amazing job with this work of functional art! This is the largest diameter tube we have ever seen! It really makes it awesome to hold so much water keeping the rig nice and heavy for the accident prone person. The base is super thick and clean with the right amount of color to really make this water pipe fire! Oh, and did we say the water percolates so great with the 20 tree perc. The welds are impeccable as well.
