Easy Through / Straw

Easy Through

Have you ever been troubled about drawing out the books which tightly stuck in the library shelves? E-pink slip is a new kind of board that helps reader to take out library books. When you insert this pink slip in the gap between two books, you can use its wedge-shaped front end to hook the edge of the book you need.
