HYDRATE THE RIGHT WAY - Drink from your Perilla bottle throughout the day to support a healthy lifestyle. Plastic bottles are not only damaging to our health but to the planet as a whole; copper bottles will benefit you and our beautiful planet. CAREFULLY DESIGNED - From the curves of the bottle, to the way it feels in your hand, to the gift-ready packaging, everything about our product has been designed with intention. We limited our branding to just the packaging and the top of the cap, ensuring the bottle has a clean, modern look. It’s essentially leak-proof, keeping the water where it should be! FEATURES Made with 100% pure copper Holds 33.81-oz. Attention: This vessel is made from pure copper and that may result in visible dark and black spots appearing. This is totally NORMAL and a sign of PURE COPPER. It is not unclean or harmful. It's a layer that forms on top of the copper than doesn't dissolve in plain water.
