▶️️These are handcrafted from pure copper and made with some of the thickest copper that can be formed by hand.

▶️️RAW copper interior for Ayurvedic Health - there are ZERO coatings or liners so the interior can ionize copper into your water/drink, and you can enjoy the many health benefits.

▶️️Interior WILL tarnish - since the interior is real raw copper, it will tarnish. You can remove it with lemon and salt or allow it to remain and simply darken the interior of your cup. The tarnish will not change the flavor or compromize copper's ability to continue to ionize copper into your drink

▶️️14oz size has a PERFECT feel and size for DAILY drinking of not only copper water, but most any cold, only mildly acidic, drinks. Once you start using this cup, its HARD to put it down, and it will be what you reach for every time.

▶️️LIFETIME WARRANTY - if any of our products fail to function properly under regular use, we will gladly replace them at no charge. We love our products and stand behind everything we sell.
