Avery J. ★★★★★

Finally a tray wide enough for my 16x20 prints without any bending. The plastic feels solid and the red color makes it easy to spot among the rest of my gear.

Edward ★★★★★

The acid-proof surface gives me peace of mind when working with harsh chemicals, and the 40x50 cm size is perfect for 16x20 prints. It handles a full day in the darkroom without any warping.

Victoria ★★★★★

Finally a tray that’s actually big enough for 16x20 prints without feeling flimsy—the ridged bottom keeps the paper from sliding around during processing. Washes come out perfectly even, and it’s held up to dozens of chemical baths without any cracks or warping.
