The resin has the expected properties. If it smells like the real stuff, burns like the real stuff, then it should be the real stuff.
I bought both this and the asafoetida resin -- both are fantastic! This benzoin resin in particular has a lovely aroma. I look forward to using it frequently in my apartment to improve its environment, and a little goes a long way -- it will last quite a while. Thank you for selling this.
