I asked the team about some custom content for my business. Although they could not help me directly, they were able to give me a couple other suggestions that may get what I need. They were very quick to respond (less than 12 hours) and very professional. An overall positive experience and highest recommendations to work with them.

Love the cards. From the designs to the touch of their new cards. The designs are elegant and strong.

Theory 11 is one of the best magic company that I have ever had. The quality of the products were always amazing and the customer service is always helpful and efficient. Would definitely recommend Theory 11!

Theory11 has amazing, professional quality, unique products not only for the collector like myself but also for a person just looking for a great product to use. They don't just stop there though... they also have top-notch customer service. They have answered all of this muggles' questions since I started collecting their products with speed, courtesy and compassion each time I have one. I couldn't be more thrilled to repeatedly purchase from Theory11 knowing they not only produce masterpiece items, but show their pride in their products with world-class professionalism whether your question is simple or complex. Can't wait my lastest purchase (Harry Potter Puzzle inbound!!!) to arrive. - Jenn 🧙♀️
