The antiperspirant compositions are transparent, phase stable, non-whitening and non-staining to the skin and clothing following topical application. Means cover the end of the optical fiber and protect the end of the optical fiber from any effects from the exterior when the connector is not inserted and release the end of the optical fiber projecting from the housing when the connector is inserted in the coupling. This structure is configured to mechanically and thermally isolate the bonding region of the electrical traces from the head slider mounting region to reduce mechanical and thermal effects of a solder ball bonding process on the article during solder ball bonding of the head slider to the electrical traces.
