【FLEXIBLE & STRONG】 NISHI builder nail gel set is highly flexible so that you can do extra-long nails with it. The flexibility also makes it stronger than other regular builder gel and remains highly similar with natural nails. The nail extension gel is strong, it won’t chip, break, or peel off easily. Please note that this builder nail gel will be more thicker than poly nails gel as it can help you to shape your nails.
