These are a great quality and easy to clean. To keep them looking like new I do recommend using Stainless Steel Cleaner & Polish. The pieces also stack well; however, I do put a towel between each piece (inside pans only). I would caution you to open the boxes well in advance of your event because you have to put all the pieces together; and keep the orange pieces to help get the inside pans apart (hence, why I put dish towels between each inside pan).
