I have a worn a particular Signature scent for over 30 years but the scent had gotten weaker over time possibly due to changes the company had made. I did research and discovered that the original China Musk from Berkeley was the foundation of this signature perfume that I have been wearing. I ordered it and was instantly transported back to the original strength and quality of my beloved signature scent. I have purchased the China Musk oil in the roll-on also the cologne and I plan on using them and layering them with my other signature scent. I tried the China Musk from other companies and this one is by far the best. Thrilled to have found it!
