Ah yes, I've been getting hounded for gas mask filters lately, and managed to snag a few of these bad boys. These are in great, unissued shape and will fit 40mm NATO threaded gas masks. Most of these are dated in the mid 2000s. These are lightweight and affordable. Get yours while you can!
I am selling these as a costume/collectible item only as they are expired and I can not attest to their CBRN efficacy.
THESE CAN NOT BE SHIPPED OUTSIDE OF THE UNITED STATES
