We want you to be satisfied, and if you’re not, we feel responsible. That’s why we have a refund guarantee for you where you don’t have to worry about trying to reseal the lid and fill up the bottle with random household items so we won’t notice you used it. We want you to use it, how else will you know if you like it? Our empty bottle promise means you can send us an empty bottle, and we’ll give you your money back. We’ll be sad you and our fibers didn’t work out, but we understand and we wish you the best.
