This is a very popular Familar mother and child health handbook case! ^_^ I bought it in preparation for childbirth, but I didn't have a chance to use it, so it's in very good condition! It's the largest size, so I think it can be used for mother and child health handbooks from any local government! It also has plenty of card slots, which are convenient for storing medical examination cards! For those who are planning to give birth soon, please consider it!
