Hans Larsen Nebra Vacuum Insulated Recycled Stainless Steel Water Bottle is a double-walled, leak-proof stylish water bottle with an inbuilt carry loop. The best part - it's made from 79% RCS-certified recycled stainless steel. Part of the CHANGE Collection, Nebra helps to contribute to Water.org - a global NGO that provides millions with access to safe water and sanitation. By giving to Water.org, you are giving a Gift That Gives Back. Nebra's double walls help keep 8 hours hot, and 24 hours cold and are both made from SS304-grade premium stainless steel that's totally corrosion-resistant. Packed in a stylish recycled box that educates about making the Change from single-use to reusable products.
