You are buying an original Soviet gas mask carrying bag complete with an adjustable shoulder strap and buttons marked "Мосштамп" (Moscow stamp). This bag measures approx. 14" x 9" (35 x 23 cm). Never used, new old stock from the Soviet military surplus warehouse. Please see the photos and let me know if you have any questions. Shipping is $9.95 for the first bag and $2.95 for additional bags. I also have Soviet gas masks, if you are interested. Thank you.
