There are 2 trays shown in the photos: a large tray and a small tray. 1) is the price listed for both trays or just one? 2.) if the price listed is just for one tray, which one, small or large? 3.) the only dimensions listed are 8" x 8" x 10". That is inconsistent with the photo. What is the height of the tray? 4.) I am assuming the 8" x 10" is the smaller tray. What are the dimensions of the large tray? Thanks!
