Grei nails are designed for rewear — with proper care, each set can be reused for up to 6 months.
For a single application, expect 5–7 days of secure hold with our jelly tabs, provided you prep and apply as recommended. Longevity depends on how you wear them — they’re made for bold moments, not permanent fixtures.

Prefer a stronger hold? Adhesive glue offers extended wear—but frequent use may weaken your natural nails. We recommend removing with care.
For damage-free removal, opt for our Jelly Tabs. They provide a secure fit and peel off cleanly—no residue, no harm. Change your nails as easily as you change your mind.
