Airbake by Wearever sheet pan. No lid. These are the best brand of cookie sheets! Not made anymore and hard to find. Do not submerge in water. Measures as listed in the photo: 15.50 x 10.50 x 1.12 I’d classify it as a “half sheet” pan. Perfect for a thin cake, bar cookies, sheet pan meals etc. Wear consistent with use but tons of life left! This will last! All photos were taken by me and are of the actual item for sale.
