Ain Stein lead replacement refills feature a structure that supports the core from the inside, due to a strong silica frame that delivers the highest level of strength and makes the lead difficult to break. With a perfect balance between strength and density, this lead makes it possible to write strong and dark strokes and lettering. Comes in a blue colour case. Made in Japan.
