# How do I access the properties of the response builder?

All response builders hold properties that were assigned to them upon creation from the request. These properties are typically the arguments that would be passed to a conventional Laravel controller and subsequently used in the code within the controller.

For example on the **ProductPage**, the **Aero\Catalog\Models\Product model**for the requested URL can be accessed as follows:

```
\Aero\Store\Http\Responses\ProductPage::extend(function ($page) {
    $product = $page->product;

    // do things with the $product model
});

```
