About Us

Welcome to Ninja Paper! As part of our goal to have a great shopping experience for you, our “Ninjas”, we wanted to share with you our company story, some of its culture, and a little bit about the people who make it happen here.



Ninja Paper is the creation of wife and husband team Christine and Michael Kupfer.  While trying to add wall design to their home, the couple found a frustrating experience awaited them.  After looking through books and books, there was just no easy way to find patterns they liked in colors that did not make their choices “special orders” that took 6-12 weeks. They also discovered that the cost of the wallpaper materials plus the installation really did not allow their budget to go too far. In fact they had to put off decorating one room for almost entire year.

They wanted to be more part of the process. They wanted to choose patterns and customize size applications, and colors, and they wanted to be able to afford it!

In other words, they wanted to be the Ninjas! 

So the couple set off around the country to research manufacturing (in the US), as well as various print, material, manufacturing technologies and process and soon after- Ninja Paper was born with the concept where YOU, the customer, gets to “Be The Ninja”!

Christine Kupfer - Co-founding Ninja

While working as an inside trader for an investment bank, Christine was not once but twice put in charge of her office redesign (yes we all thought that odd since she was in fact a trader). She actually enjoyed the experience greatly except the process.  These days Christine mostly works with designers for commercial spaces as well as for hospitality design and restaurant design. She is a superb hockey mom to two young boys and hockey wife to an older boy.

Leslie Castromayor - Graphic Ninja

As the very first hire at NinjaPaper.com, Leslie handles a variety of graphic design, site content and even some print production. Appreciating art, fashion, and all areas of music that are beyond her years, Leslie considers herself a connoisseur of “cool”.  As a graduate of the Illinois Institute of Art with a degree in Fashion Marketing Management, Leslie hopes to continue kicking butt at Ninja paper, and perhaps open her own boutique marketing firm one day. As a youth she closely followed the graffiti art scene and had a poster of a painting created by famed street artist Steeze. This poster is what inspired her to go into a creative field and never look back!
