A 3-slot thread card intended as an “Emergency” sewing kit.
Load with your favorite high-quality thread and tuck a needle or two behind it for a low-profile sewing solution perfect for reattaching buttons or fixing a splitting stitch while you are out. Fits well in a wallet when loaded with an appropriate amount of thread.
*Works best with coarse threads, in the case of slick or thin thread I reccomend wrapping with a rubber band or similar.
