bob bong hit it on the head. a grinder/kif catcher is worth its weight in GOLD! if anyone smokes top notch dank you need to invest in a space case or similar grinder. btw if you have ever taken even a 1 hitter of kif you know it is intense! ive been raving about mine for weeks. just think by grinding it you catch the crystals tha twould normally rub off on your fingers or whatever you break it up on. so you might as well collect it and smoke it up. i normally cant wait morethan a few days beofre i empty it. but im a head!
