This is no ordinary drink holder - the KODAMA drink holder is custom fit for our large and small zomes. Made from a solid billet of aluminum, CNC machined and polished for a lifetime of use. No flimsy pressed metal here. For the shelf material, we have partnered with ACRE - an amazing new material made from rice hulls but built for outdoor use.. Everything is sourced in the USA and made by hand at our shop in Oregon. Enjoy your favorite beverage without fear of spilling - the drink holder has you covered. Cheers!
