It does what it says really. I used it to put something my girlfriend really liked inside - she's really impatient so I had fun watching her :)
Be careful not to let it close once you remove the thing that covers the latch, as mine closed by accident when I first opened it!
(If you do close it by accident, Id suggest using a white-board marker to plot the route to the exit, to save you some time and frustration!! you can then wipe the pen markings off before giving it to the lucky recipient!)
