Our Small Bistro Set is crafted of Maidenii wood which is the top of the line in the Eucalyptus family. FSC Certified Maidenii is a high-density tropical wood which provides extreme durability in the most miserable of conditions. All pieces require minimal maintenance. Without any maintenance a rich silvery patina will develop. If you wish to maintain the original honey brown color, you may do so with a light sanding or application of teak oil annually. All the hardware is rust resistant.
