Nail Quail Strong Will anti-nail biting click pen — 7ml invisible bitter polish, odorless & vegan

This compact, brush-on pen offers a discreet, no-sheen solution for nail and cuticle biting. The formula dries clear and odorless, so you can apply it anytime without obvious lacquer or shine. It’s made in the USA, vegan-friendly, gluten free certified, and formulated without formaldehyde, parabens or ethyl acetate — built to be used on nails, skin around nails, and other affected areas.

How quickly will I feel the deterrent effect?

The formula is formulated to be immediately aversive on contact, helping interrupt the biting habit as soon as you apply it. Because it’s intensely bitter, most users notice the effect the first time it’s used.

• Instant bitterness when contacted with tongue or teeth
• Drying to a fully invisible finish, so the effect is noticeable without visible polish
• Click-pen design enables fast, one-handed application in seconds

What safety and ingredient details should I know?

Strong Will avoids common harsh solvents and preservatives; it contains no lacquer, formaldehyde, parabens, or ethyl acetate. The formula includes plant-derived, soothing ingredients to ease irritated skin after frequent biting, and it’s produced from responsibly sourced components.

• Free from lacquer, formaldehyde, parabens, and ethyl acetate
• Certified gluten free and vegan-friendly
• Contains organic extracts like aloe, eucalyptus, ginger, wintergreen, and oat kernel for calming support

How do I apply it and how long does one pen last?

The click-pen mechanism dispenses the bitter liquid to a small brush tip for controlled, targeted application. Apply directly to the nails, nail folds, or any affected skin; allow it to dry clear. Longevity depends on frequency of application and personal use, but the 7ml size is compact for carry and repeated touch-ups.

• Click pen with brush-on applicator for precision
• Apply to nails, cuticles, or any area that needs deterrence
• 7ml size designed for portability and repeated daily use

Can children use this product and are there any age recommendations?

Because Strong Will is intensely bitter, Nail Quail recommends use by ages 4 and up only with adult supervision. Keep out of eyes and avoid ingestion; follow common-sense safety for young children.

• Recommended for ages 4+ under supervision due to intense bitterness
• Not intended for ingestion; avoid contact with eyes
• Store safely out of reach of unsupervised children

Who is this for: Strong Will is for anyone trying to break habitual nail biting or skin picking who wants an invisible, odorless deterrent. It suits adults and supervised children who prefer a portable, brush-on format without visible polish or harsh chemical solvents. Ideal for people seeking a plant-forward formulation with calming botanicals and clear ingredient exclusions.
