This is the Dungeons & Dragons officially licensed Demon Idol Dice Tower, based on the iconic figure originally painted by D.A. Trampier for the cover of the first-edition D&D Player's Handbook. This was a GameStop exclusive released in 2021. This is brand new, never used, and still sealed inside the box (that is, the box itself never had sealing tape on it, but the dice tower inside the packaging is in a styrofoam insert that is still taped and unopened).

[Note: My assumption is that most people are buying this to use/display the actual dice tower, but in case you need the outer box in perfect condition, you should know that there are a couple of dents on the top edge of the box. (You can see them in the photo of the back of the box: one on the corner on the right side of the photo, and one midway back on the left side.)]
