Most LEGO enthusiasts would probably appreciate a nice box of bricks instead of random LEGO branded merchandise, but if you must torment them, these old BIONICLE pens are looking like a decent deal and even offer a sort of building experience.

At 20.00 USD with free shipping, these BIONICLE themed pens make for a nice small collectible to leave in their box and display shelf where a BIONICLE MOC may not be appropriate. If you plan to open and use the pen, they offer a nice distraction since they can be unscrewed to access and customize the decorative top-half of the pen. Although these pen-exclusive elements are not particularly compatible with the normal LEGO system, you can still find pens from a number of other LEGO themes with compatible elements to mix and match.
