I made my own Pipes Bong and oners out of steel and titanium

my bad I meant anodizing. Im not sure if they use acid I thought it was just a water based solution but aluminum isnt my thing so I may be wrong.

 

some new designs

 

ok so I tried selling them on ebay and it was immediately taken down because it is drug paraphernalia so if you want one just pm me and we can use paypal by itself
