Sensitivity Test KitIf youre sensitive to traditional gel nail products and curious about trying Gellys semi cured gel wraps, our Sensitivity Test Kit lets you test it for yourself before buying a full set. Apply a few gel nail strips, cure them under UV, and see how Gelly feels and wears. If youve previously experienced sensitivity to gel polish ingredients, you can use this kit to do a small patch test first before moving over to Gelly.
