About the bullet casings we use in our kits. We use only fired casings and recycle them. Some casing's will have chambering marks, scratches, and minor dings on the cases that contribute to the character and authencity of each pen you make. Most scratches will sand or polish out, and most dings will be minimized by polishing. We do not use casings that in our opinion would be objectionable to most pen buyers...
