At USA Pen Company, we craft pens and pencils in a small utility workshop of a house in Elk River, Minnesota.  We use exotic wood and acrylic to hand make our pens. Our selection over the past few months has evolved into an assortment of contemporary designs... Come take a look at our collection and choose your favorite to either gift to your loved one, or keep all for yourself! 

All our pens and pencils are handmade in the United States of America (USA).

Welcome to the art of pen and pencil making at USA Pen Company. 

Would you rather have synthetic plastic or the feel of rich natural wood in your hand? We make our pens with carefully selected exotic wood from different parts of the world! 

Do visit our Gallery and Lookbook. If you like any pen currently not available in our "BUY NOW!" page, email us the details and we will specially handcraft and ship it to you within 14 days of your order. 

We look forward to serving your needs. Thanks!
