The Mac 7 to 13 Dab Rig by Mob Glass Works is a dab rig that features a seven slit in line  percolator and vibrant colors. This is a classic commentary on the 7 to 13 style of dab rigs, though they can still be used for flower. The Mac 7 to 13 style 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 water pipe is a solid experience for amateur smokers and professionals alike.
