The DNA of Kos Fragrances goes back more than a century, spanning four generations of passion for scent and craftsmanship. For over 100 years, the Kos family carried a vision of creating something unique in the world of fragrance yet the leap was never taken.
That changed with Wessel-James Kos known online as wesseljamesk. After building a strong following on social media, he saw the perfect moment to bring this dream to life. With youthful energy, the right people around him, and the courage to take a risk, Wessel-James decided to make it happen.
Today, Kos Fragrances focuses on offering high-quality perfume accessories. These early collections are helping us build the foundation and resources needed to launch our first signature line of Kos Fragrance perfumes, a vision over 100 years in the making.
