Open the velvet case and there is the Pocket Mirror, sold as an object of the Glass School. Its advertised talent is precise: it will show the card a reader is avoiding. A difficult act of attention has become something that can be bought and carried home.
The Glass School rejects it. The inventory calls it a later commercial literalisation of reflection, though rejection has done little to end its popularity. A small, convincing object travels easily. So does its promise.
In a demonstration, imagine tilting it towards a spread. A sliver of card appears, then a patch of ceiling, then the fingers holding the frame. The view changes with the hand. Which glimpse counts as the revelation? The seller’s account can make almost any of them significant.
There is still a question someone might choose to ask while looking: what am I reluctant to consider? The Glass Court and the High Priestess give that question imaginative company. Optional theatre can help a person approach it. Turning the mirror towards a partner and announcing their concealed motive makes a different claim, one the reflection cannot support.
Close the case and the object is portable again. The question, if it has become useful, will take longer to put away.
