Snug storage case to keep microwave accessories from moving

We bought this to secure all microwave-related accessories. It holds the revolving glass bottom plate and every accessory that came with the Pebble oven, with some extra space for dishes. There are lots of similar products, but this exact size—15” outside and 14.5” inside—makes for a snug fit. You have to push a little, but it fits firmly inside the microwave and keeps everything from bashing around in transit.
