Used many times

I have used this pochade box many times sitting at my desk and en plein air. I own the medium sized box, 8.4 by 11.25 inches and routinely paint 9 by 20 inch panels on it. It fits easily in my backpack with tripod and camp stool strapped to the outside allowing me to hike to wherever I want to paint. I have the two side trays that I strap to the box with the included rubber straps. The magnets actually help them stay in place. I found the box to be well made and have had no problems with any of the functionality. Photo is my typical setup.
