We wanted them to be unbreakable. We wanted to minimize their slipping and spilling their content when the yachts are heeling. We wanted them to resist to scratching and continue looking nice after the first year of use. We got all we wanted and more. We also got award winning design by Marc Newson and environmental protection by their being 100% recyclable, BPA-free and Melamine-free. Visit the manufacturer’s website palmoutdoor.com.au and you will be convinced too, why we think that it is worth importing them all the way from Australia!
