If you are purchasing new MICRO side trays or have a tray with the internal measurements of 6" x 6 3/16" this is the Neutral Gray Bamboo side tray palette for you.  

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

Note: The Neutral Gray Bamboo Palette is only available for the smaller tray in a nesting set.  The easel will not lock properly if you choose to install an expandable palette in each side tray.
