A rubber eraser and method of fabrication is disclosed. The mixture comprising a rubber eraser composition comprising non-crosslinked polymer, plasticizer, stabilizer, thixotropic filler and pigment; wherein the non-crosslinked polymer is a basic material ranges from 20% to 40% by weight; the plasticizer ranges from 30% to 50% by weight; the stabilizer ranges about from 2% to 5% by weight; the thixotropic filler ranges about from 20% to 40% by weight for the rubber eraser mixture to form into a soft clay-like mixture; and pigment ranges from about 0.5% to 1% for coloration of the eraser. The method includes the steps of heating the eraser mixture for at room to 50-70 degree C.; mixing the mixtures and kneading cutting or pressing to form into a desired shape; and placing the obtained product into an oven or hot air device at temperature 120° C. to 130° C.
