So I sanded a hole in a special edition liquor bottle with funky custom art and this was the matching mouth piece. A crown, if you will. Despite it's light look at feel, it's a solid piece of glass with a wide bowl area for a deceptively good volume.
In person the color is a vibrant lavender/purple which initially jarred me but was well received by my company. Once the smoke hits the bubble, it fades slightly to a barely bluer lavender that's great too- just different.
The stem is a perfect fit, no movement, and overall it's actually larger than I expected. Fitting piece of hardware for your collection.
