This design is printed with eco-friendly plant-based inks directly on the stainless surface. Tumblers include BPA-free leak resistant, easy-to-clean and easy-close hammer lid.
Triple insulation reduces condensation and keeps your drink hot for up to 8 hours or cold for up to 24 hours (use caution with hot liquids). Copper-lined 18/8 stainless steel construction is durable, and material won't retain tastes or odors.
For best results, hand wash with soap, water and a scratch-free sponge. Towel dry immediately to help preserve decoration. Do not soak or use cleaning materials (bleach, chlorine, etc.) and do not put in dishwasher, freezer or microwave.
