See my other listings for other colors, and for replacement lenses for the Canadian C-3 gas mask:
4A / KYNG / GP-5. (DOES NOT FIT this 4A clone: https://www.665leather.com/gas-mask.html)
Replacing lenses is very easy on these masks.
Israeli: Loosen screws on collars and remove. Pop lenses outs. Put new lenses in. Put collars back on and tighten. Detailed instructions included in shipment.
Russian GP-5: Using a flat screw driver, slightly lift the fingers on the metal band around the lens. Remove the fabric tape. Pop the lens out. Put new lens in. Put metal collar back on the "eye". Using a pair of long-nose pliers, crimp the fingers back down.
NOTICE: These replacement lenses are sold as novelty items. They are not designed to resist impacts, chemicals, or biological agents. They do not provide any protection against UV, lasers, or any other form of light or radiation.
Shipped via untracked first-class mail.
