The Mac 20 Dab Rig by Mob Glass Works is a dab rig that features 20 tree percolators and vibrant colors. This is a classic commentary on the tree perc style of dab rigs, though they can still be used for flower. The Mac 20 Dab Rig is an excellent piece that allows a user to pay the price for high end glass, but have the experience of a heady water pipe itself. This waterpipe is a solid experience for amateur smokers and professionals alike.
