Martin Universal Mijello Fredi Weber Peel Tray, 12.75 X 9-Inch, Off Palette, Acrylic, Multicolour, 22.86x34.41x0.63 cm

This is the best tray for acrylic paints that I have come across yet.It wipes clean with warm water if washed straight away after using, and dried paints peel off later fairly easily.Obviously It will not keep paint wet for using at a later date as the more expensive ones with filters in, but it gives a much better purchase for your brush than on a paper surface.I would recommend any new acrylic painter to try one of these palettes.
