Alpaca, also known as German Silver, is the traditional metal of yerba mate gourd and straw artisans.  It is loved not only for its beauty but for its resistance to corrosion and ease of maintenance (simply clean with a dry towel to shine). 

18k gold plated tip adds beauty and eases the heat on the lips.  Removable filter cleans easily.
