It’s unlikely that your No. 2 pencil could equip you with information about your tire tread gauge. The Messograf is the leader of multipurpose pens—constructed of chromium-plated brass, the pen includes a caliper rule, a ruler, and a thread scale. Plus, it’s a badass ballpoint pen with a compartment that allows gel refills, so you two will never have to part ways. Don’t let anything go unmeasured: you’ll never have to settle for an educated guess again!
