This ad features (1) one 18.8mm HORNED SLIDE 5 HOLE BUILT-IN SCREEN ECONOMY SLIDE glass slide bowl for your water pipe with a cone shaped bowl and a clear glass finish. Over-all this slide bowl is about 2" long (includes 1" long joint area), 1 1/4" outside diameter at the top surface of the cone and has a 18.8mm male joint size with the shown gripping ring. The actual tobacco bowl part of the slide is a deep cone shape that is about 3/4" inside diameter at the top surface and about 3/4" in depth with a 5 hole built in non-removable glass screen at the bottom. This item is an economy-grade glass item and as such will vary in exact size and features (but will always fit a 18.8mm joint). We have seen variation in the size and location of the built-in screen openings. Note: The pictures show multiple examples of the slide bowl but the price is for 1 (one) slide bowl. Economy quality glass construction.
