The portions represented by solid lines in the drawings are the sections for which registration as a partial design is sought; articles involving this design are leggings; separate elements (e.g., tape) into which a mineral (e.g., a powdered healing crystal) has been incorporated are applied to the articles, or a coating material containing a mineral (e.g., a powdered healing crystal) is printed onto the articles to provide them with mineral-containing sites (areas where minerals are present); the diagonal lines shown in the reproductions 1.7and 1.8form no part of the claimed design; in the reproductions 1.7and 1.8(reference front-side diagram indicating areas where the mineral is present and in the reference rear-side diagram indicating areas where the mineral is present), the areas executed with diagonal lines indicate areas where the mineral is present.
The broken lines in the drawings depict portions of the leggings that form no part of the claimed design.
