About this product
Nail Quail Strong Will Anti-Nail Biting Click Pen is a brush-on anti-nail biting pen with a ridiculously bitter formulae that dries completely invisible with no smell or sheen. The 7ml pen is made in the USA and applies one-handed, so you can brush it onto nails, cuticles, skin and other affected areas in seconds. It is recommended for ages 4 and up.
Does the Strong Will pen need a UV or LED lamp?
No. Strong Will is not a gel polish and no lamp of any kind is involved. It is a brush-on liquid in a click pen that dries on its own and leaves no visible sheen, so there is nothing to and nothing to buff away afterwards.
How many coats of the pen for full coverage?
One even pass with the brush is enough to coat the nail and surrounding skin. Because the formulae dries invisible, you cannot judge coverage by looking at the surface the way you would with a coloured lacquer — apply it thinly and evenly, and let it dry.
An invisible, bitter anti-nail biting pen in 7ml
The pen format keeps the formulae contained and ready to use. A click at the base feeds the brush, which is small enough to work along the nail edge and around the cuticle without flooding the finger. Strong Will dries completely invisible, has no smell and no sheen, so it does not change the look of bare nails. The 7ml size is the only volume stated for this product, and the pen is made in the USA.
Applying Strong Will for a daily routine
Click the pen to load the brush, then sweep it over the nails, cuticles and any other affected areas you want to cover. The one-handed action means you can do it without setting anything down, which suits a quick top-up during the day. Because it dries without a sheen, it can sit under a regular mani or be worn on bare nails.
Pairing the pen with your usual nail routine
Strong Will is not a top coat and it is not a colour, so it does not replace either. Think of it as the step that goes on the areas you want to leave alone, applied before or after your usual polish routine depending on how you like to layer it. It contains no lacquer, formaldehyde, parabens or ethyl acetate, and it is certified gluten free.
What is in the Strong Will formulae?
The formulae includes Organic Aloe Leaf Juice, Organic Eucalyptus Leaf, Organic Ginger Root, Organic Wintergreen Leaf and Organic Oat Kernel, and it is described as vegan-friendly. It is free from lacquer, formaldehyde, parabens and ethyl acetate. No other ingredients are listed for this product.
