This is a large Base. Made for 29"-40" hookahs, 15 inches and the opening is approximately 1.6 inches
Glass bases are mouth blown and sometimes have air bubbles as evidence of this fact. Artisans hand paint each glass base, making every one as unique as the artist. This results in a 100% unique finished product that may not look identical to the photo. It also means that sometimes the paint may have a slight smudge, a line may not be perfectly straight, or you may see the artist's brush strokes.
