MAJ: to be perfect, this product should have a sort of rubber around the stone pouch that does not let him down. because obviously, as the wet, he slipped and fell it broke into several pieces Looks like Bourvil "it will work bcp less bine now. OLD: This product is really good and cheap. It can be used several times daily. I do not have any irritation or itching under the arms. Just wet the stone and get wet under the arms to pass the stone. There for several years of use. It can also go to the crotch as there are no side effects! I will certainly cut a small piece to carry with me to use in the day. Conforming delivery thank you Amazon.
