Filter? Pfft screw that. Trust me i have wielded the bowl it can be a bitch. a mini bic and a jay is were its at. Like i said before i make the jays in advance and then when i gotta go toking i bring with me the jays. expecially if ur like me and toke in public places pre-made joints rule. In other words when ur a yougin and toke behind dumpsters n shit like me lol. U need the joint so when your done u can walk home without carrying a dime bag and resin'd up bowl. I think i have explained enought lol :dance:
