Bongs are RtL 6 or 8", roughly 12" then the tallest bubble one is 20". The yellow blue bowl is about the size of an Xbox controller. Two glow in the dark I broke the one at the stem so bought another but cheaper one.
Those are a couple of Fatbudda glass pipes and a couple bongs. They make thick glass as the name implies.
I know they're huge and far as a pipe goes, best one I've owned. I own so many because I like em clean so easier too have a few instead of cleaning them all day.
