Volume Mask

You must prepare musk before using:
1. Warm it up by hot water or hair/industrial dryer.
2. Bend along the guides.
3. Warm it up again (do not burn yourself) and make sure it`s sits tight on the face.
4. Split cosmetic cotton sponge on half (or use whole if you have strong lungs) and insert to intake valves.
5. Cut 17mm diameter circle from some light film and insert to outtake valve. Screw the cover of outtake valve to fix the film (You can trim the pillars on the lid, if the film is thick and does not fit.)

Whats changes:
1. Two intakes for better breathing
2. Added outtake for better breathing (you can just plug this hole if have no material to make valve)
3.Reinforced rubber mounts
4. Enlarged nose flaps, for big ones faces (must be ok for smaller faces to)
