The LEGO® Lockable Notebook with Gel Pen is perfect for LEGO® enthusiasts of all ages. It includes a hardbound square-shaped notebook measuring approximately 15.8 x 15.8 cm. The notebook is made with FSC-certified paper and has 176 to 192 sheets (meaning 352–384 pages), with subtle ivory-colored lines for comfortable writing.

The cover is hardbound and features embossed LEGO® 2x2 bricks on the front and back, providing durability and a classic LEGO® style. The notebook also has an integrated elastic band that can function as a bookmark or to keep it closed when not in use.

The package includes an authentic LEGO® Gel Pen with a medium 0.7mm point. The pen has an integrated LEGO® 1x4 brick, allowing it to snap into the special slot on the notebook and serve as a "lock" for secure transport or storage.
