Rated 5 stars by real reviewers
My nails actually feel stronger after a few weeks. This isn't just a coating that flakes off.
The pen is so easy to use. I keep it on my desk and apply it without thinking about it.
Skeptical at first, but the difference in how my nails bend versus break is real.

Questions, answered.
How do I use it?
Twist the base until the brush loads, apply to clean, dry nails and cuticles, and use it twice daily. It absorbs in seconds and leaves no greasy residue, so you can apply it and carry on.
When will I see a difference?
The photos at the top of this page show the same nail before use, after 30 days and after 90 days of twice-daily use. Nails grow slowly, so give it a full cycle.
What is in the formula — and what is not?
An aqueous, odorless nano-keratin formula that strengthens the nail plate while it conditions the cuticle. Free from formaldehyde (formol), parabens and organic solvents. Made in the USA.
How long does one pen last?
Each pen holds 3 ml in a high-capacity reservoir, enough for a full 45-day cycle at twice-daily use. The click mechanism doses it evenly, so there is no dripping and no waste.
Pen or Shield — which one do I need?
The Pen is the 3 ml twist applicator you keep in a bag or pocket for on the go. The Shield is the same nano-keratin formula in a 15 ml bottle with a brush for use at home. The Complete Bundle has both.
Is it in stock and where does it ship from?
Yes — it is in stock and ships from our facility in Florida. Shipping is free on orders over $55.
