Ok, I'm really satisfied by your service, that I decided to leave a feedback.
I'm residing in Turkey, I paid for the item (Black PBF gas mask) on May 4 (and there was a problem during transaction on my part, so again, I thank them for their understanding) I received the package on May 14, just as they said about 10-14 days of delivery, it was delivered to me in 10 days time. Good.
The package was filled with stuff (paper) to prevent any possible damage to items. The mask and the bag was in good condition, and both filters were sealed. The only slight thing was that the mask was a bit dusted (i wasn't expecting it to come out all shiny, the dust is to be expected, they were produced back in the 70s and I think they were kept in an old soviet warehouse and the guys selling these didn't played with them and kept them as they are) so I spent a couple of minutes cleaning the dust and then insert the filters. It's "easy and quick" as they said, and once I inserted the filters, I put on the mask and it fitted perfectly.
I recommend using some powder on the inside of the mask (that's a recommended for all rubber/latex clothing/masks) both to prevent the rubber from dying by your sweat and to wear it comfortably. Short hair and a clear (beardless) chin really helps. After removing the dust from inside and outside with a wet towel (don't use chemicals, that will wear out the rubber), the mask started to shine (literally). You can also obtain spare filters for the mask so that you don't run out of filters if needed.
to conclude, I'm really glad to have purchased from sovietarmystuff.com, they delivered what they promised and in good condition.
There are a couple of shots;
