I'm having success keeping my pre-mixed oil paints in a Masterson palette, which is like a flat Tupperware rectangle with lid.
I don't worry about the seal, though it might help. I put my paints on a piece of glass that fits inside the palette, then pour water over the paint until each pile is covered. The advantage is that the paint keeps a LOT longer this way. If I have to, I can put the whole contraption in the freezer and it keeps even longer. I lift out the paint to put onto a wood palette when I ready to use it.
