Introduction Timeless. The Ecridor Chevron houses an inverted v-shape design on the six sides of its palladium-coated body. These chevrons are engraved by a diamond and elegantly match its palladium-coated finish. The Ecridor Chevron mechanical pencil is equipped with a high-precision mechanism. The quality of the 0.7 mm Graphite leads and the convenience of the replaceable eraser positioned under the push button will be appreciated.
