Both cups are marked Argentina Alpaca on their bases and each feature silverplate with three balled feet and come with an Industria bombilla straw. The silverplate is tarnished and the interior of the darker cup is flakey and needs to be cured; otherwise, they are in very good vintage condition. To cure the gourd, scrape the dry flakey material from the inside with a spoon, fill the gourd with loose Yerba mate, pour in hot water, let gourd sit for 24 hours, empty a...nd scrape again, rinse well and you are good to go! If you have any questions or would like additional information or photographs, please don't hesitate to contact us. Many thanks, Chance Landing
