Self Loading Dice Tower Product Manual
This dice tower comes almost fully assembled, you just need to snap in the 2 pegs as shown in video.
When using the tower, pull the lever all the way down to load the dice. Let go of the lever to allow the tray to fall and catch the dice. Try not to use too much force while pressing the lever down to load the dice into the tower. If you use too much force, the dice will fling over the tower and make a mess. It may take a few tries to get use to the mechanism, but once you do it will be easy.
