This box is a piece of art. Beautifully constructed and functional. It has one major drawback that forced me to buy another pochade …. the magnet system made it impossible to use painting knives. The magnets are so strong they would grab my blades if I got close to them, scraping them across the painting surface. I had to buy a second pochade from another vendor and now my alla prima sits on a shelf to be admire as a fine sculpture.
