Good size, easy to clean

Fits my sink perfectly. Cleaning is a breeze since the surface is smooth despite the ribs. Would give 5 stars if it came with a lid, but that's a minor issue.

Essential darkroom gear

Been using this for three months now with D-76 and fixer. No staining or warping. The matte black finish really helps when checking contrast under safe light conditions.

Great value, slight chemical smell initially

Works perfectly for my darkroom setup. It had a faint plastic smell when I first opened it, but a quick wash removed it. Holds enough solution for multiple sheets.

Sturdy and deep enough

I was worried it might be too shallow, but the depth is ideal for submerging 10x12 paper completely. The material feels much thicker than cheaper alternatives I've used before.

Perfect for large format printing

This tray is exactly what I needed for my 10x12 prints. The black plastic is thick and durable, and the ribbed bottom helps agitate the chemicals evenly without scratching the paper.

Reliable for film and paper

I use this primarily for sheet film development and it handles the volume well. The construction is solid, and it stacks nicely with my other trays for storage.

5 FAQ

Q: Does the ribbed bottom damage delicate photographic paper?

A: No, the ribs are molded smoothly to facilitate even chemical flow and agitation without abrasion. They are safe for all standard photographic papers.

Q: What are the exact internal dimensions for fitting paper?

A: The internal usable area is designed to comfortably accommodate 10x12 inch photo paper and film sheets with room for agitation.

Q: Is this tray suitable for color processing chemicals like C-41?

A: Yes, the high-impact polystyrene material is resistant to standard color and black & white processing chemicals, including C-41 and E-6 solutions.

Q: Can this tray withstand hot water for cleaning?

A: Yes, it can handle warm water typical for darkroom cleaning (up to 95°F). However, we recommend avoiding boiling water to prevent potential warping.

Q: How many of these trays can be stacked together safely?

A: The design allows for secure stacking of up to 5 trays when empty. We recommend nesting them carefully to avoid stress on the corners.
