Review on 🌈 Hiware 12-Pack Rainbow Metal Straws Reusable with Case - Stainless Steel Drinking Straws for 30oz and 20oz Tumblers - Dishwasher Safe, Includes 2 Brushes by Antoine Dean

They don't taste like metal. They don't bend easily. These are very strong metal straws and I'll probably die before they wear out. I bought the color Rainbow and got a lot of compliments. For people who don't know how to achieve rainbow coloring on the surface of food grade or surgical grade metals like stainless steel and titanium, here's an explanation. The colors of the rainbow are on the surface but not painted. Anodizing is an electrochemical process that transforms a metal surface into a decorative, durable, and corrosion-resistant anodized coating. Anodizing is done by immersing aluminum in a bath of acidic electrolyte and passing an electric current through the medium, in this case a stainless steel straw. I have titanium and stainless steel earrings anodized in a variety of colors including rainbow. Anodizing food or surgical metal is non-toxic. I hope that was helpful. Have a nice day.
