Police always searching the mandem and were always ballsing the pack. It gets long and mandem have to smoke spliffs that smell like ballsack. I found a certified solution. This has been TRIALED and TESTED in a real life section 60 stop and search and it's completely police proof (for now). 
 
Pack of 3, the sizes are a bit tight, so don't grab them if you like loose fit boxers that allow ur shlong to breath.
