We just received from Sanrio, three die cut Hello Kitty erasers in a locking carry case. We see die cut erasers from the Chinese producers. The Hello Kitty die cut set pictured is produced by Sanrio Japan, but made in China. Iwako and Dream Zensinsyoji do not make die cut erasers but rather use molds to create the three dimensional shapes of their erasers.
Extruded erasers are squeezed out of a extruding machine much in the same way that you squeeze toothpaste out of it's tube. Then the long extrusion is cut in into pieces.
In the One to Forty erasers section, there are many die cut erasers, some of them very good. Here we have some 12 inch long extruded eraser ropes that have not been cut up.
