Paterson Film Developing Tray 10x12 White

I’ve used these trays for about a dozen rolls now and the ribbed base keeps the 10x12 sheets perfectly flat even when I get a little rough with the agitation. No warping or slipping at all despite the heavy chemical use.

The polypropylene is thick enough that it doesn't flex or buckle when I slosh chemicals around, and those ribs underneath keep it planted on my wet counter. Handles 10x12 paper just right, and cleanup takes a minute.

The ribbed base on this tray grips the table nicely even when there's splash, so I don't accidentally knock it over mid-develop. It feels sturdy without being too heavy, and the 10x12 size is perfect for a single sheet of film.
