Dear Greg
We're genuinely sorry to hear about your experience with our sunglasses, and we appreciate you bringing this to our attention. This is certainly not the quality and durability we strive to deliver.
Can i ask if you returned the Mangrove Jack to the source you purchased them from, it's possible that the sunglasses might be too narrow for your head, causing strain on the hinges. We value your input, and we're here to help. Please contact our online team ...online@brighteyes.com.au if you want to discuss this matter further.
