Paterson 塑膠顯影盤 - 適用於10x12吋相紙（3入組，每色各一）PTP335

The three different colors make it so easy to keep developer, stop, and fixer separate without any mix-ups. These trays are rigid enough to hold a full 10x12 sheet of paper flat without bowing.

The plastic feels properly tough, not flimsy like some other trays I've used, and the color coding for chemicals is a real time-saver when I'm working fast in the dark. They sit flat on my bench without any wobble, and cleanup was a breeze since the chemicals didn't stain the surface.

The textured ridges on the bottom keep my 10x12 paper from sliding around during agitation, and the three colors make it impossible to mix up developer and fixer. They feel solid without being too heavy when full of chemistry.
