These needles have large, collapsable eyes. A little pressure and the eye opens for easy threading, but squeezes down flat when going through beads.
From the manufacturer:
Collapsible Eye Needles are flexible and are particularly nice for stringing beads and have collapsible holes. Extra-spring wire is kink-resistant and has a specially designed eye that automatically collapses and instantly reshapes when it is pulled through the bead. The large eye is easy to thread and accommodates many sizes of cord. Five-inch length makes stringing beads easier and the 2 1/2 needles are great for seed bead projects. 4 per package. Imported.
