Customer Reviews
Amazing cards, love them!
I just got my Avengers Playing Cards and they are incredible! The detail on these is just insane, pictures don't even do them justice. The tuck box is so cool and the cards themselves handle perfectly. I can't wait to show these off. I'm already planning my next order, probably the Star Wars ones. Totally recommend!
Got a deal on the box set
I was looking for some nice playing cards but didn't want to overspend. I saw they had a luxury box set for the Lord of the Rings Playing Cards and it was a pretty good price compared to buying the individual decks. I also signed up for their newsletter and got a little extra off, which was a nice bonus. Shipping was free because my order was over $75, so that helped with the budget too. The cards arrived quickly, maybe 5 days, and they look and feel really good. Definitely felt like I got my money's worth with that bundle.
Good cards, slow support
I ordered a few decks, including the new Spider-Man Playing Cards and a brick of Monarchs. The ordering process was smooth, I just picked what I wanted and checked out. It took about 8 days for the package to arrive in Florida, which was a bit longer than I expected, but not terrible. The quality of the cards is, as always, top-notch; the Spider-Man deck felt great right out of the box and shuffles perfectly. My only minor issue was with a question I had about my tracking number. I sent an email to support and it took almost 3 days to get a response, which felt a little slow. Overall, happy with the product, just wish support was a bit quicker.
Consistent quality, returning again
This was maybe my fourth or fifth order from theory11. I picked up the Harry Potter Playing Cards and a few single decks of Artisan. Just like my previous purchases, everything arrived well-packaged and the card quality is consistently excellent. They always feel good for cardistry and magic, no complaints there. Shipping was pretty standard, about a week to get to me. It's why I keep coming back, I know what I'm getting.

Share tips, ask questions & help fellow shoppers save more
Hey, wondering how long shipping usually takes for a deck of cards? I'm in NYC and need them by next weekend for a gift.
Are their cards actually good for cardistry, or are they more for just collecting? Like do they hold up well to shuffling and fanning a lot?
