Made from food-grade 18/8 stainless steel, these tumblers are resistant to rust, corrosion, and stains, making them ideal for both indoor and outdoor use. They are also BPA-free, ensuring that no harmful chemicals leach into your drinks.
Key Features of Penguin Stainless Steel Vacuum Insulated Tumblers

3. Durable and Rust-Resistant Stainless Steel
The 18/8 stainless steel construction ensures that the tumbler:
- Withstands regular use and rough handling
- Resists rust, tarnish, and stains

4. Leak-Proof Lid with Secure Seal
Penguin tumblers often come with leak-proof lids that include rubber gaskets to prevent spills. The lids feature a sliding or flip-top design, making them convenient for one-handed operation.
5. Sweat-Free and Ergonomic Design
Thanks to the vacuum insulation, the outer layer remains sweat-free, preventing water rings or slippery grips. The ergonomic shape of the tumbler fits comfortably in hand and fits most car cup holders.
