pic is pretty much spot on here.. taken for reference beside what your average bar/diamond pony looks like (the threading on these tends to go all the way into the dome like this one on the right in the pic) as you can see the one on the left is nothing but domeglass. Well over an inch and a quarter here. You wont find one with more domeglass-nice bubble at the base too. Check the view original to get a good idea. Forty dollars shipped.absolutely guaranteed, thanks for looking.
