WordPress: how to hide toolbar in post editor?

I have a Custom Post Type (Products) in my WordPress web site.

This is a WooCommerce Product, if it’s necessary to know.

I need to hide toolbar (1) into wp-editor on Add Product page. Also I need to hide “Add media” button (2) and “Visual/Text” tabs (3).

How do I hide them?

Maybe it make sense to change this WordPress Editor to the textarea with the same value of “name” attribute with using of some hooks?

Answer

I have found this solution:

    function hide_toolbar_TinyMCE( $in ) {
        $in['toolbar1'] = '';
        $in['toolbar2'] = '';
        $in['toolbar'] = false;
        return $in; 
    }
    add_filter( 'tiny_mce_before_init', 'hide_toolbar_TinyMCE' );

But it hide toolbar everywhere, because this is “filter” but not “action”. How do I hide it only on Product (Custom Post Type) Add/Edit page?
