This kind of glass is most popular with hardcore pipe collectors that want a piece more for collection & display than daily usage. the community calls these pieces "heady glass" for the artwork that the glassmaker has put into it. Anything goes with heady glass. twist, turns, aliens, frogs, big, long intricate deigns, & anything the glass blower can think of to stand out.
Grab one of these and take it out on those special occasions then, place it back on the self to be admired by all.
