The needle end is 1" long and triangular with thickness ~0.04" from the base of the triangle to an edge.The other end is ~1.2" long with a right angle bend at the end and has a circular cross-section with approx diameter of 0.072"The middle section is ~1.3" long with a tapering diameter down to 0.06".
