Breath Reducer Valve (Screw Fit)
This amazing little device screws into any Gas Mask with a 40mm screw thread (including the S10, Israeli and Russian Gas Masks).
Once screwed in, the tiny 6mm hole is all that the wearer can breathe through. It literally reduces the amount of breath the wearer can take!
You can even add cotton wool inside the device and add some of your favourite aroma.
A great introductory breath control device, you'll love the Breath Reducer!
Sold as a novelty item.
