This black shower oil rig is manufactured by the makers of Black Leaf who are certainly known for engaging users with their astonishing bong designs and quality. This oil rig has a built in downpipe with a black shower head diffuser. The stylishly crafted main water chamber has an overall diameter of 38 mm which then subtly reduces into a slimmer and more refined curved pipe. The black tint of the glass diffuser accentuates the flared mouthpiece, the matching base, bowl and diffuser. This item comes complete with nail and glass dome.
