This handy kit provides just the tools you need to hone your spy powers and start tracking coworkers’ comings and goings. Your sleuthing gear includes a micro listening device for those not-to-be-missed conversations between bosses. You also get two discreet mirrors which can be used singularly or can be built into a simple periscope—essential for snooping over cubicle walls. And don’t forget the two-in-one invisible ink pen and decoder that lets you record classified information without being discovered.
