Is all stainless steel the same?
Unfortunately, all stainless steel is not created equal and many lesser bottles employ low grades of stainless steel or use too thin of material in an effort to drive low prices. Pura Kiki bottles are crafted of high grade, food service #304 stainless steel (also known as 18/8) with 0.5mm thick walls. Known for its resistance to corrosion and staining, and antibacterial properties, #304 stainless steel is perfectly suited for use as a beverage or infant bottle. In fact, milk pasteurization as well as many commercial food transport and storage containers use this type of stainless steel and have for decades. Stainless steel is a safe and durable choice.
