Vintage Anchor Ovenware Popcorn Popper/Steamer/Roaster for Microwave. We've used this for popcorn and a steamer but have not tried roasting, but you can see instruction booklet for details on all features. All parts are easy to clean, and we enjoyed using this and would keep but need to do a major downsizing. Great way to save money by buying popcorn kernels in bulk versus prepackaged microwave popcorn
