Kemira Finnish M-95 Gas Mask w/ Manual. I believe the size is “regular” which apparently fits like a Medium/Large. Mask is NEW WITH DEFECT (the drinking tube port cover/cap is cracked/broken as shown which is a common problem with these masks). Mask may have some minor scuffing/dust from storage. The drinking tube is unpunctured/unopened. Mask/filter not intended for actual protective use. If you choose to wear it for costume/etc. I recommend washing/scrubbing it first in lukewarm, mild dish soapy water with a soft rag and air/towel dry (do not hang dry/dry in the sun). Let me know if you have any questions! Items are stored in a smoke/pet free home. Please be sure you want the item before purchasing.
