This portable clip will help you keep your books open wherever you go. It comes in a handy pen-shaped format that unfolds into an H-shaped book clip, with one clip on each side. The separate clips ensure that your pages are held down even if the two sides of the book are uneven. The top of each clip is also short and translucent, so it won't get in the way of any text.

Each clip can hold papers about 2.5 cm thick. With the clips turned in, the overall book clip measures approximately 15.1 cm long.
