Grav 14mm swiss downstem
I want to see my overall experience on my grav piece the Swiss down sound so far so good I'm loving each individual Swiss whole the way that it diffuses my smoke I just love it yes I do not own a brand name piece yet it's a Ricky bing bong but I feel this is the first stepping stone got to have a good downstem before having to try to have a good glass bong I've been keeping an eye on the Stax Helix grav collaboration might get it pretty soon thank you once again you guys at 4:20 science
