I will send you some samples with your package . Normally they are about 3 or 4 oz and are called solid shampoo bars . Here is a link to one I have tried and loved and why I decided to make them . http://www.etsy.com/view_listing.php?listing_id=33537671 I will be making a solid conditioner too ( when my forgotten ingredient gets here from the USA). They are fantastic in every way ,no excess packaging , not full of water , easier on the planet , easy to take on a plane and they sure clean your hair and they last a long time . Thanks everyone for your kind words
