      Unusual Raw Materials
      Expanding the pallet of avid amateur-perfumers.
      This website is the result of my own attempts at getting hold of aroma chemicals that were hard to come by. At least in the amounts required by hobbyists. My goal is to offer an ever-changing portfolio of fairly unusual raw materials in order to continuously expand the pallet of avid amateur-perfumers.
