These are just wonderful, they just needed a bit of buffing off the smoothness in the mixing tray areas so the water and paint won’t bead. The two I received didn’t lay completely flat when opened and placed on a table. But I did bend them very slowly and very carefully with a bit of gentle force to help them loosen up a bit so now they lay completely flat and they have so much room for mixing! There is so much room for a large selection of both gouache and watercolours, planning to divide some warm and cool watercolours up in one palette and then my favourite gouache colours in the other palette. I love that I can take these with me wherever I want, so I can always have the same colours and know where everything is. I do have one very tiny magnetic wooden palette with four spaces that is held open and together with a binder clip that I use for a reduced/minimal colour palette when I’m wanting to travel lighter/more discreetly than these two larger palettes would allow. I love these!
