Stainless steel square trays, commercial use, professional use, deep type, shallow type, set of 3, bulk sale, retro

These are stainless steel baking trays that have been in my family's kitchen for many years. Please purchase all three together: two deep trays and one shallow tray (with a caveat).

① (Deep) Size 12: 32.3cm x 25.5cm
② (Deep) Size 15: 29.5cm x 22.8cm
③ (Shallow): 34.5cm x 24.5cm

① and ② were used in an actual shop for many years, so they have a commensurate amount of wear, scratches, and dents.
③ is new and unused, but due to poor storage, it still has the plastic wrap on the back and had rust. When preparing it for listing, I washed the back, but was unable to remove it completely. (This is why I've noted it as having a caveat.)
Please check the photos for damage and condition.

That said, they are still in usable condition. How about them for those who are looking for these items or want to stock up on tools affordably? These are used items that have been stored at home for a long time, so please consider them with your understanding.
