Polskibrit

For me it's the reference Russian Leather with emphasis on birch tar. Extremely smoky and realistic, it almost hurts your eyes to smell it. You feel just like near to some birch tar pit near to a tannery in a remote Siberian village over winter. Almost unwearable on its own in the same way City on Fire/T-rex can be a bit too much but not funky unlike these two - just really austere. But it layers beautifully with brighter, citric fragrances. I tried one spray of it with two sprays of Eau Sauvage Parfum 2017 on top of it and the result is gorgeous. It adds a lot of depth to it.
