when i bought my first piece i got a bowl and a case, and at first i kept only the bowl in the case, but now, i still have the bowl and the case, but inside i usually keep the piece, the mini swiss army knife with the knife, scissors, file, tweezers, and toothpick, a lighter, and no more than an 8th of weed. then when i travel i just take the case if i have some green or plan on getting some. I also have the top part of a DVD case(the part where the booklet goes) as a surface to keep the green off peoples tables or other surfaces where dirt and weed gets lost in, i bring this if i plan on smoking.

The case works well, ive had cops look right at it and think it was no more than a sunglass case.
