The thinner the package the better, but stiff enough not to show the cylinder. I've used two. The first was tape, thin card board and a plastic NRA memberships card. Worked OK till it got a little sticky. Then I got an Uncle Mikes no.3.
I've used this every day for 4+ years. Your choice of britches will make or break this dance. Short go pockets on Wranglers leave the thing peeping out the top and show a bulge. How about relaxed fit somethings with pleats?
Depends on how you style.
