This ad features a 14mm CURVACEOUS shaped glass slide bowl for your water pipe that is over-all about 3 3/4" long (including the 1" ground joint area) and has a 14mm male slide joint. The slide also has a robust single clear glass curved horn for easy gripping. The actual tobacco bowl part of the slide is a deep cone shape and 3/4" in diameter at the top surface and about 3/4" depth. This item is a hand made glass art item (vs. exact machine made duplicate) and as such will vary in exact size and features (but will always fit an 14mm joint). The outside diameter of the slide bowl is around 1 1/4" in diameter at the top section by the bowl opening, 1 1/8" at the lower expansion chamber which tapers to 7/8" in diameter just above the 14mm male joint. The grip horn is about 3/16" thick x 1/2" in length.
