A metallic article is produced by furnishing one or more nonmetallic precursor compound comprising the metallic constituent element, and chemically reducing the nonmetallic precursor compound to produce an initial metallic particle, preferably having a size of no greater than about 0. In order to prevent the degradation of the organic EL layer by water, a first inorganic film, an organic flattening film, and a second inorganic film are formed on an upper electrode. Each sleeve module has a body with a selected length and has two opposed ends that are internally threaded. The user, when notified by this signal, may input to the set top box a request for a second program, such as an interactive program or application. The accessory has a display unit, a processor, a communication interface and a housing. Reusable envelope structures can be formed and kits can be formed for converting existing envelopes to reusable envelopes in accordance with the present invention.
