seems to be popular with people who want as little metal interference with their tea as possible. (If you are extremely metal sensitive you might try our bamboo bombillas.) These stainless steel are also finely made, strong and beautiful; very modern. They open in various ways. The stem itself may be cleaned out with our bombilla cleaning brushes, available on our mate accessories page.
Stainless steel is becoming harder to find--for whatever reason (global economy; trade with China, etc. etc. etc.)--so treat these like gold... well, almost.
