Palette Garage (16 Inch) Keep your oil paint fresh for weeks. Clove oil in the end caps prevents oxidation and hardening of paints. Air tight plastic tube with removable paint tray. See videos on the website. End caps with felt wicks absorb clove oil but keep clove oil from touching paints. Includes a 1/2 ounce bottle of clove oil -- enough to last a year (we've upgraded from the tiny bottles we used to include.) Attach the paint tray to your paint box or palette with the included spring clips or Velcro tabs.
