School backpacks with a pencil case-book

Pencil case-book

— a pencil case (a case for pens and other stationery trifles), made in the form of a book, consists of two halves folded together in a closed state. Inside there are loops and other "seats" for objects carried in the pencil case. Pencil cases-books are usually more capacious than another variety — pencil cases-cases (see the relevant paragraph); However they are more bulky, but they have a flat shape, which is often more convenient than a round case. Yes, and access to the contents in the "books" is more convenient, in the open state such pencil cases do not have "secluded places".
