A separate page with a description for the brand

I can do it like this, but maybe you have a more beautiful solution?

function rudr_url_redirects() {
	/* in this array: old URLs=>new URLs  */
	$redirect_rules = array(
		array('old'=>'/shop/?filter_brand=rosenthal','new'=>'/rosenthal/'), 
		array('old'=>'/contacts/','new'=>'/Contacts/')
	);
	foreach( $redirect_rules as $rule ) :
		// if URL of request matches with the one from the array, then redirect
		if( urldecode($_SERVER['REQUEST_URI']) == $rule['old'] ) :
			wp_redirect( site_url( $rule['new'] ), 301 );
			exit();
		endif;
	endforeach;
}

add_action('template_redirect', 'rudr_url_redirects');

I know about this page. But I need a separate page for brands with a description. I got there when I clicked on the brand logo on the product page.
