This ad is for ONE (1) 14mm EMERALD GREEN glass water pipe slide bowl with a horn and ball. The horn is clear glass with a pale frosted green colored accented ribbon twisted inside and the ball is clear glass with the same color mushroom inside. 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 single hole 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 3/8" 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). Note: The pictures show multiple examples of the slide bowl but the price is for 1 (one) slide bowl. Excellent quality glass construction and good looking.
