The occupiers in Ukraine use these gas masks.
This is one of the modifications of the civilian gas mask GP-7 that was supplied to the occupier army.
There is nothing particularly special to say about it, it’s a standard item that should work well against harmful gases.
For us, it’s a great exhibit and an opportunity for creativity in using it in different styles by the masters of our project. You can see several exhibits based on this item in our collection.
