Frequently Asked Questions
As these products are sold as a bundle, you cannot return individual formulations. The bundle will need to be returned as a whole.
No, the bundles all come as completed sets and formulations cannot be swapped for others.
The bundles are a great introduction for those who are new to RATIONALE. The smaller sizes allow for discovery and trialling a product without having to purchase the full-size product. As not all formulations are available to purchase at smaller sizes, there is not a comparable discount available.
