This is a pouch measuring 12.5 cm in height and 18.5 cm in width. When you open the button, there are two compartments inside, and there's another compartment on the back, for a total of three compartments. Please use it to store things like maternal and child health handbooks, or medical record books (*^^*) I think it can also be used to store masks, etc. It's handmade, so I've made it carefully, but it's a hobby project, so please understand and consider purchasing. I'm listing this on behalf of my mother (Ohamun), who enjoys handicrafts (*^^*) There are no smokers or pets. #Ohamun's handmade items
