Grav Labs dual function Inline 13”

I Purchased this pipe a few months back on this website actually. Nothing wrong with this whatsoever, I’m just in the process of moving and I have at least 45 to 50 pieces. I can’t move with all of these. This comes with a 14mm dome and a 14mm slide. Has an in-line perc and I think the other perc is called a UFO perk or something like that? Function is pretty good, however, you do have to plug up one of the ends depending on which function you’re using.
