The Nuki Yali Stick Hair Extension System is a hand-tool set for installing stick-tip (I-tip) and micro-link hair extensions. Tools in this category typically include a pulling/threading needle, used to draw a section of natural hair through an extension's ring or loop, and a plier-style tool used to open, close, and crimp the connector that secures the extension to natural hair — all without heat, glue, or chemicals.

This is a professional extensionist tool, intended for salon use rather than first-time at-home installation.
