Finished blanks are supplied tumbled to soften off any sharp edges and are ready to stamp. Unfinished blanks (supplied with a protective peel off coating) will require polishing / tumbling and may have sharp edges.
Due to the nature of copper and brass, any surface marks or dullness that appear on the surface pre or post tumbling can be polished up back to a high lustre with a suitable product.
