With the Interchangeable Mechanical Pen and Pencil, it doesn’t matter if you prefer writing with a pen or pencil. This interchangeable pen and pencil lets you have the best of both worlds. You simply swap its components when you want to change between using a pen and pencil. It’s perfect to keep in your bag or at your desk so you always have a writing utensil nearby. You won’t have a bunch of out-of-ink pens and broken pencils cluttering up your workspace anymore. You can choose from three finishes: brass, black oxide, or brushed chrome. Whichever one you pick will make you feel stylish when you sign your name on your lunch bill. And to ensure that your interchangeable writing instrument doesn’t get scratched, add on the carry case for protection.
