What size distribution tubing are you using?
I'm using the woodpecker junior drippers and their output barb is 1/8" not the more common 1/4". I initially had dripping because I was using distribution tubing that was too large
^yup, im the same as you. i got some free blunt wraps from my local head shop and threw away the blunt wraps and kept the little plastic tube for storing joints
i think they are kind of gimicky but they arent really that expensive. id say they are worth a try if you cant afford to just buy a better bong with better diffusion
that looks more than 12 inches, maybe its just the goofy angle that the picture is taken but it looks like the seller doesnt know how to work a tape measure
