*Permanent Collection: As the title implies, these perfume oils are created with the intent of perpetual availability. PC perfume oils are created in-house and stored in larger Master bottles. As a rare exception, a PC perfume may contain a component that we can no longer create or attain, and if reformulation would compromise the original recipe, a PC may be discontinued. Each of the PC perfumes is available in 2 mL sample vials or 5 mL **amber bottles. As long as the components are available within the blend to create in our Studio, the perfume will remain in the Permanent Collection. **Please note we are slowly changing over to a 5 mL cobalt blue bottle - 5 mL amber bottles will be stated until then and shown in the photos of said collection until the upgrade/change to cobalt blue has occurred. Each Collection will continue to expand; there is no eta on new perfume debuts in the PC. We do update our Facebook page and Thoth's Scroll for recent updates.
