FA: Three Clean 5 X 7 Trays to Develop 4X5 film -- or other use
 

Here are three used, but like-new, 5X7 trays -- handy for lots of
darkroom uses, but just right for tray-developing 4X5 film. Each is
colored so you can always use the right tray for the right chemical,
and each is colored to reflect less light than white trays.
