Review on 🧲 Copper Water Bottle 34oz - Dark Embossed, Leak-Proof, Ayurvedic Pure Copper Vessel: Ideal Copper Bottle for Sports, Fitness, Yoga, Harnessing Natural Health Benefits by Paul Bijeaux

This is my first copper purchase as I am more aware of my water consumption and value. I did a magnet test to make sure it was real copper and it passed. However, after cleaning with lemon/vinegar and salt according to the company's instructions and information online. I found a light substance on the top of the lid (see attached photos) that I had to scrape off with my fingernail. Everything was on the lid. I didn't find it on the rest of the canister and I hope I didn't miss anything during my inspection. I hope that after drinking this I will not get sick with this defect that I have found. There are several calls that worries me that it will be used or returned. In addition, it is airtight, easy to clean, easy to hold and beautiful.
