It is only 2 inches deep and now that I went to the kitchen, smaller than a brown sugar box. It is the same size as a box of Ronzoni Elbow Macaroni.
Way too small for popcorn and chestnut roasters that I have seen are usually solid on the bottom. If you have ever roasted chestnuts they take a while and this would not last that long. Screen over a fire for more than a few minutes will become red hot and melt. This thing shows no sign of ever being in a fire. Maybe it was never used.
I think it is for dropping a small caged creature on someone and the long handle is for you too be at a safe distance when they react. Like a spider, frog or mouse.
