What is a Refill?

A refill is not a discount program. It's not a loyalty scheme.

It's what happens when you finish a MONOLITH product and choose to return—to the formula that worked, to the system that didn't fail you, to intimacy without compromise.

You used every drop. You return with your Hydra Certificate. You pay refill pricing. You receive a new product. The cycle continues.

Simple. Honest. Sustainable.
