If you are purchasing new MICRO side trays or have trays with internal measurements of 6" x 6 3/16" or 6 3/8" x 6 3/8", these are the side tray palettes for you.  

The STRADA Expandable Palette for the MICRO Side Trays is half the weight of glass, unbreakable and just as easy to clean.  

Note: The easel will not lock properly if you choose to install an expandable palette in each side tray.
