i saw this beautiful black and white bong a year ago and been looking for it online ever since. I know for a fact that they are sold online, just can't seem to find it. someone told me he saw it on Dh gate but again I didn't managed to find it. I thought of posting it here and see maybe you guys could worded it differently or do something to find it. (In the photo it's the middle one)
Take this pic on your phone and show it to the people at the smoke shop you saw it at, I've had a lot of luck doing that sort of thing when I'm hunting. That is your best bet. Googling black bong and searching through thousands of them will not get you anywhere.
Not sure if this is helpful but it's a reverse image search so you just put in the image and it finds it it's 6 bucks to try it out if you really want this bong here's the website Membership Levels | People Search - SocialCatfish.com
