Leakproof Product Ingredients

At Knix we put a lot of care into the products that we make. Our community trusts us with some seriously intimate problems (think periods and leaks), for which our team works tirelessly to provide great solutions that meet their needs and empower them to do more of what they love. With that trust comes our commitment to be transparent about how we make our products, inclusive of what goes into making them.
