The LEGO Stationery Locking Journal uses genuine LEGO 1x6 plates and a LEGO Gel Pen with its 1x4 plate and tile to secure the book covers. This keeps your cool and clever notebook and pen set locked, secure and ready to go anywhere. The notebook features a cover made of a smooth, supple material and embossed LEGO 2x2 brick details front and back. Use the integrated elastic band as a bookmark or as an alternate method of securing the notebook without the gel pen. This ingenious LEGO Locking Notebook makes a great gift for anyone!
