The passports you have to buy. I think they are about 10 bucks. Maybe a little more now. We bought those as something different to do. I think we have over 10 masks per child!! lol
If you have never done the masks before, Id skip the passports. That will be enough for the kids to do in every country. You get a stamp on the stick, and a decoration from that country. PLus you can color and add things at every stop. Masks are free! And you can pick on up in any country!
