Prinz  stockbooks are simple bound stamp albums of heavy cardboard pages with strips to hold the stamps. They are available in an endless array of sizes, shapes and colours. Some have rigid, book-like bindings, others are equipped with flexible double-hinged pages. Prinz stockbooks are useful for storing stamps not yet given space in printed albums, as well as keeping duplicates and extra stamps for trading. They are also recommended for starting topical collections or ”safe-keeping” your most valuable stamps in deposit boxes. Comes in Red, Blue and Black.
