Addicted to webtex!

Have any of you ever used one of these? <a href="http://cgi.ebay.co.uk/School-Bag-Pencil-Case-Camoflage_W0QQitemZ9309070370QQcategoryZ15729QQssPageNameZWDVWQQrdZ1QQcmdZViewItem">http://cgi.ebay.co.uk/School-Bag-Pencil-Case-Camoflage_W0QQitemZ9309070370QQcategoryZ15729QQssPageNameZWDVWQQrdZ1QQcmdZViewItem</a> They are pretty good but I can't fit my ruler inside,  does anyone know of any other camo school solutions?  5.56mm
