Islamia's older “Opus Silk”, “Opus Easy Clean”, “Opus One” etc. names remain preserved. A current manufacturer product is linked only where exact identity is established. Where identity is uncertain, the page remains legacy-labelled and points to current manufacturer intelligence instead of making an unsupported rename.
Use dedicated pages for products, brands, services, local information and technical guidance. Manufacturer-specific claims remain source-gated; customer reviews are treated as experience evidence rather than technical proof.
