Strong nails start with healthy cuticles. That's where your nail growth starts, at the root. If your nail edges are dry, sensitive or inflamed, you'll notice it immediately on your nails. The Wonderpen mini immediately soothes that sensitive spot. With a powerful blend of jojoba oil, shea butter and almond oil, it nourishes and repairs your cuticles intensely. These rich oils soothe inflammation, deeply hydrate and make your nail contours supple and healthy. You'll feel the difference after one time. You'll see the difference after a week.
