Definition & Meaning of "slipcase"in English

What is a "slipcase"?

A slipcase is a protective box or cover designed to hold and protect a book or a set of books. It is usually made of sturdy material and is slightly larger than the book or books it holds. The slipcase often features a design or artwork that complements the book's cover and provides additional protection against damage. It slides over the book, covering the outer sides and sometimes the top and bottom, keeping the book safe from dust, scratches, and wear.
