Food-grade certified
The Sherba thermos is made from 304-grade stainless steel the same standard used in professional kitchens and medical equipment. Safe, non-reactive, and built to last.
No coating. No plastic. No compromise.
Unlike painted or coated bottles, the interior is bare stainless steel meaning nothing leaches into your water. What you taste is pure yerba mate, nothing else.
Rust-proof and non-porous
Stainless steel doesn't absorb moisture, bacteria, or odors. Your thermos stays clean, hygienic, and fresh-tasting session after session.
