Aluminum is a lightweight metal so it can be prone to dents if it takes a good hit or if it takes a fall, but dents are just blemishes and are battle scars to prove that we are truly recycling our aluminum bottles and producing less waste! Our Kapitolyo plant has a strict quality control process that will make sure every NANU bottle we sanitize, recycle, and fill can still hold 500ml and will not be at risk for permanent damage.
