When you’re bored at the office and the IT department has really limited your surfing options, taking apart all of your pens starts to seem like a good idea. Design studio Fraser Ross started to wonder if maybe putting a pen together was just as interesting and time-consuming. They created the DIY Pen to keep your idle hands busy.

The DIY Pen is a flat-pack product that can be sent in a postcard-size envelope. The pieces all pop out and slot together easily to create a uniquely-shaped pen that your office mates will never be able to claim is theirs.

The final stage of assembly involves using a hair dryer or oven to shrink the rubber down to a tight fit over the wooden discs. The project is an exercise in pairing up unusual materials. Plywood and heat-shrink rubber aren’t often used together, but they work together marvelously in this fun consumer product.
