I had switched to Urban Sketching, wanting to paint quicker whilst painting en plein air. I needed a palette that would not rust as I live by the sea. It needed to have smooth edges and fit into the palm of my hand for comfort. I am absolutely delighted with this Art Toolkit Palette. The base has a magnet holding in the pans. Even the tiny pans are not to small for my travel paint brushes. They hold plenty of paint for several 31x23cms 12x9 " paintings on Saunders Waterford paper.
