No. Semi-cured gel nail strips are designed to harden enough to fit and hold their shape on your natural nails, but they are not intended to become as rigid as acrylic or press-on nails.
For the best results and longest wear, we recommend trimming the strips to match your natural nail length rather than using them as extensions.
If you would still like a little extra length, we recommend extending no more than 2mm beyond your natural nail edge and applying a top coat to help seal and reinforce the free edge.
