"An ounce of prevention is worth a pound of cure." With Ben Franklin's famous quote in mind, we developed our blister blocker. It's a fragrance free, crystal clear balm that glides on smoothly and without any greasy residue. We've formulated an all-natural anti-friction balm that prevents skin irritation. Our blister blocker is free of nasties like artificial dyes, silicones, PEGs, parabens and pthalates, is totally fragrance-free, is never tested on animals, and is made in the USA. Creates an invisible protective barrier to prevent blisters and chafing Dermatologist-recommended Ideal for breaking in new shoes Lightweight—perfect for on-the-go use Clear Non-toxic, made of only all-natural ingredients that nurture and moisturize skin Lasts for up to six hours Stops blisters before they happen We rely only on pure ingredients like castor oil and candelilla wax, a vegan alternative to beeswax that's derived from the leaves of a small shrub native to the American southwest. Both of these ingredients score a squeaky-clean green from the environmental watchdog group EWG, which means you know they're extremely safe. INCLUDES 1 0.15 oz/4.5 ml tube
