The password box is a unique addition to the ROKR collection, allowing you to hide surprises and test your assembly skills. The practicality of this model makes it the perfect gift for any holiday.

The rotary knob on the front is used to enter the password and open the box. The password is set during assembly and cannot be changed once finished. With 810 choices between 000 and 999, you'll have to follow the manual for details on the 190 unavailable combinations. The back of the box features two holes for a key, which is used to open the inner tray.

On the top of the box, you can rotate the gear to open a small space, and at the bottom, you can record the password you set. The laser engraving provides instructions on how to enter the password to open the box. Anticlockwise 2 circles to digit 1, clockwise 1 circle to digit 2, and anticlockwise 0 circles to digit 3. Then the box will open and reveal its surprises! This is the perfect addition to your ROKR collection, so don't miss out on the Marble Spaceport LGC01 and Treasure Box Model LK502 DIY Brain Teaser.
