This ad is for (1) 4" MINI BLUE HAMMER dry glass pipe with a unique stacked sphere stem made up of blue spheres separated by a white stem in between. This is a very unique and attractive hammer style pipe. The pipe is very stable sitting on a flat surface due to its extended base. The styling of the pipe is sleak and aerodynamic and the glass is smooth and glossy. The over-all length of the pipe measured parallel to the stem from the end of the barrel to the end of the stem is about 4", the diameter of the main stem is about 1/2" with a first sphere that is about 7/8" in diameter and a second sphere that is about 1 1/8" in diameter closest to the mouthpiece. The main barrel is 1 1/4" in diameter at the base x 2 1/2" in length (parallel to the barrel length) and tapering to about 7/8" in diameter at the bowl area. The shoe area is 1 1/4" long. The tobacco bowl is on the smaller side and is a hemisphere type and is about 1/2" in diameter at the top edge, and about 3/8" deep with a single hole at the bottom.
