What I am attempting to achieve is showing only certain pages inside a loop. 3 certain pages, no more, not less.

I have attempted a lot of things however i cannot complete it.

<?php
    $special_tabs = new WP_Query(array ('post_type'=>'page','post__in'=>array(100,102,104)))
?>

What this may, from things i understand, is it shows a range of pages after which includes individuals ID's there too.

<?php
    $special_tabs = new WP_Query('page_id=100');
?>

Which shows just one certain page, it does not offer the showing of variety of different IDs.

I am sure I'm not the very first person to possess such specific needs and I am certain there's a comparatively simple method to achieve what I am attempting to achieve, however i cannot develop an answer in order to locate one. Can anybody help me with this particular?

Thank you ahead of time!
