If you've already received a Custom Blend Recommendation, order a free sample of your Custom Blend in the Roller Oil product (you cover just the shipping cost).
 
This may help you decide if your Custom Blend recommendation will be right for you but keep in mind that all OTW blends are created with purpose first, always. Formulas are based on the benefits each oil brings, not their fragrance. (Luckily, they all end up smelling pretty fantastic!)
