Mix a color, paint for a while, and save the rest for another day. This 50 ml glass jar from Mercurius has a white screw-on lid to keep mixed watercolors fresh for days between painting sessions. Line up several jars for a tidy wet-on-wet painting palette, with each color in its own small pot. The jar is also useful for holding glue, ink, beads, or tiny desktop essentials.
