This pipe is part of our Simple Collection. Beautiful White lines surround a colored thick line and together they wrap around the pipe to make a great piece. This item is a fumed color changed and a has a flat mouth end. 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!
