"It is true that Pura manufacturers in China, as do all other stainless bottle manufacturers. However, we employ a vastly different manufacturing process than virtually all of our competitors:

• Pura does NOT simply source existing designs/products from vendors in China. Our products are unique to Pura, were designed by our in-house engineering and product development team and backed by more than 15 patents and patents pending around the world (including the USA, China, Europe, etc)
• Pura owns all the tooling and molds for our products so we control the tolerances, design, and ultimately function of our products.
• Pura employs our own on-site (in China) inspections to ensure all products meet our exacting standards
• Pura executives personally visit, inspect, and help set-up our manufacturing lines. Our execs have travelled to China twelve times in the past three years"
