TOTO SPARES, TOTO PARTS, TOTO SPARE PARTS, Concealed Box Mini Unit Concealed Valve TBN01001B 84818020 As of my last update in January 2022, there isn't a widely known product specifically called the "Concealed Box Mini Unit." It's possible that such a product has been introduced after my last update, or it may be a niche or custom product not widely documented. However, based on the name, one could speculate that the Concealed Box Mini Unit might refer to a compact storage or security solution designed to be discreetly hidden from view. It could be used for various purposes such as hiding valuables, concealing electronic components, or organizing small items. Without more context or information about the specific product you're referring to, it's challenging to provide a detailed description. If it's a newly introduced product or a specialized item, I recommend consulting the manufacturer's website or product documentation for accurate information.
