I recently purchased this item, but I'm selling it because I already have something similar. I've used it about twice, and it's still in very good condition. Please check the photos and only purchase if you're comfortable with the condition. Compatible with 20-24cm diameter frying pans. Specifications/Materials: Body: Aluminum alloy, Surface treatment: Anodized Color: Silver Steam rises from the center hole, warming the inside of the steamer. It's lightweight and easy to handle, made of aluminum, and has a hook hole for hanging storage.
