Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
Just having this in the bath makes all the difference in how tired I feel and how warm I am, so I find it incredibly useful. I used to add bath salts and magnesium to my bath, but with this, it feels like I have everything I need! It also helps relieve coldness.
I bought this after reading reviews. It warmed my body and made me feel warm after using it. I also gave it as a gift to a friend.
It's truly amazing, but when I add these, I stay nice and warm for a long time after bathing, regardless of the water temperature. My bathtub is small, but when I add three pills as instructed, I feel like my blood is fizzing and improving from my extremities while I'm soaking. There's no scent, no color, and the texture of the water barely changes. Sometimes I want to be energized by the smell of white water, but because this is colorless and odorless, it's great for use by everyone from babies to adults.
A friend recommended it to me, so I started using it as a treat. I wouldn't say it dramatically eases my body, but even after using it just once, I felt a little refreshed the next day.
It warmed me to the core. It's a little pricey, so I only use it on special occasions!
