Dusedo Gasmaster Gas Mask Empty Filter

Empty filter canister for gas masks with standard threading (40 mm) so it can be combined perfectly with our gas masks and gas mask hoses.
 
As our gas masks are intended as fetish items / play items only, these canisters are empty and unsuitable for respiratory protection. But apart from the great added look, it is easy to imagine the possibilities of using these canisters to reach aroma heaven.
