This ad features a 5" BLUE GLASS COIL TUBE pipe made from borosilicate glass with a unique blue glass coil inside a glass tube (that can be filled with water...DO NOT FREEZE) with a removable 14mm slide bowl. The piece also has 2 small resting feet on the underside of the glass tube so the pipe will free-stand. Note what looks like an air hole on the left side can be used to fill the chamber with water (BUT DO NOT FREEZE, THIS IS NOT A FREEZE PIPE) and the air control is done by removing the slide bowl. Since the slide bowl is a standard 14mm joint size it can be interchanged. Keep in mind that these pipes are hand made and they will have natural variations in color and contour that will make each unique, but always beautiful. This pipe is about 5" long and features a removable 14mm glass tobacco slide bowl that is about 3/4" diameter x 5/8" deep. The coil tube stem of the pipe is about 1 1/4" in diameter which tapers to the flat mouthpiece as shown. Great gift for you or your friends - enjoy! This pipe is for tobacco use only. THIS IS NOT A FREEZE PIPE
