This ad is for ONE (1) 14mm NITRO VORTEX glass water pipe slide bowl with a horn and ball and a built-in cross-bar screen. The horn is clear glass with a white and tangerine colored accent ribbon twisted inside and the ball is clear glass with a white mushroom inside. The blue color is a metal flake while the other hues are normal glass coloring. Over-all this slide is about 2" long and has a 14mm male joint size. The actual bowl part of the slide is a cone shape that is 3/4" diameter at the top surface x 3/4" deep with a built-in cross-bar screen at the bottom. The horn is about 1 1/2" long, and 3/8" in diameter at the bowl tapering to about 1/8" at the end. The ball shape is about 1/2" in diameter. This item is a hand made glass art item and as such will vary in exact size, color and features (but will always fit a 14mm joint). Excellent quality glass construction and good looking.
