What is a flexibound book?

A flexibound book, also known as a softcover with flaps or a flexible binding, is a book that has a cover made of a flexible material, usually a thick paper stock or cardstock. Flexibound books are similar to paperback books in terms of flexibility but typically have a higher quality cover material and construction. The cover of a flexibound book may have flaps that fold over the front and back covers, similar to those found on hardcover books, providing extra protection and a more polished appearance. Flexibound books are often used for special editions or higher-end publications that require a durable yet flexible cover. They offer a balance between the affordability of paperback books and the durability of hardcover books.
