Our reusable bottles are labeled with care using bio- based calcium carbonate, derived from marble mining waste (80%), together with recycled high density poly- ethylene (20%). Marble based labels give a paper-like material feel that is tear resistant and waterproof. No trees, water or bleach is used during the production process and the material can be recycled in the conventional recycling stream. The labels are removable so you can use the bottle like any other reusable bottle. Enjoy!
