This Dritz brand hummingbird needle threader includes a cover (that can easily be flipped up or down) for the needle threader, a cutter for easy cutting of threads, and a lanyard hole to make sure you don't lose this threader with your other stitching supplies.
The slot in the needle threader portion of this tool is small, so it works best for only threading one or two threads through a needle. Threading more than two threads may not be easily possible with this needle threader.
