GULL Diving Mask LANZE - Brand: GULL - Accessories: Case, Instruction manual - Color: Bright Mint Thank you for viewing. I purchased this new and used it for about 20 dives. The LANZE logo on the top of the frame and the silver mark in the center are faded. The silicone part is in good condition and has no yellowing. There are some traces of sunscreen remaining. The field of view is wide and bright. It can be used for both diving and snorkeling.
