Tricky Drawers Box - Wooden Brain Teaser Puzzle

This is a very challenging and appealing wooden brain teaser puzzle.
Contains four pieces that interlock inside the box.
Getting the 4 drawers out of the box requires a series of "sliding moves." For some it seems like impossible to get this one apart, but this is only half of the battle.
NOW try to get them back into the box, this task is much more difficult.
Makes a great gift for the talented puzzler.
