Bingo. These “Insanus” series pieces were designed to show off Ser Jacopo’s ability to drill airways at “impossible” angles/paths. I can’t say from experience whether this one would pass a pipe cleaner or not, but i wouldn’t be at all surprised if it did. You could always ask the seller to check it out.I would think the opposite; the draw hole still has to be at the bottom of the bowl, so its has to be set up in a way where the hole somehow curves down to the bottom of the bowl.
I predict it will sell this week.
