It will be better if there's a rubber or some kind of elastic on each pocket to hold the filters in place. Be careful, filters might fall off when opening the case.
Adorama Filter Case for Cokin P size filters is very good for the Cokin P size plastic filters, but I wouldn't use it for any large glass filters because the sleeves aren't tight enough to hold the glass filter in if you should open the case upside down by accident.
