As it contract & it expand

This book shelf is so applicable to my daily life! My books and magazine are expanding like madly, especially after last weekend. I swoop my bank clean in exchange of knowledge! Oh!

Let me introduce to you, Rek the bookshelf!

It is a bookcase that grows with the book collection, the more books, the bigger the bookcase. The zigzag shaped part slide in or out to accommodate books in the resulting voids. Regardless of the quantity, the bookcase will always be full. Also, the books can be arranged according to size. The narrow size are excellent for magazines.
