These sherlock pipes are fritted for a beautiful look. Fumed throughout for a color changing experience. Fumed stripes throughout the length of the pipe. It is fumed, meaning the more you smoke the more the clear part of the glass will change colors. This pipe will grow with you and evolve over time to look completely different! Clean the pipe to make it look like when you first got it and start the color changing process all over again! This glass item is individually hand-blown and beautifully handcrafted.
