## Questions & Answers

**Q: What are the dimensions?  Does it hide the cards completely?**
A: Hi - it's 2.2" wide by 3.0 inches tall. As the picture demonstrates, it does not completely cover the cards to help facilitate accessing the cards, however, you can be sure that the card numbers are completely or nearly completely covered (depending on card type). The last 4-5 digits being visible poses no security risk - these are the same digits that credit card companies use to identify your accounts publicly and are useless without the entire card number and code on the card back.Happy to answer any other questions!Jenny

**Q: Want to buy this for a stocking stuffer. What does the packaging look like?**
A: It's actually really nice. I couldn't find a picture but it looks almost like an Apple package - smooth with some shiny/silver areas. I'll try to take a picture when I get home. Definitely look like a gift (I got mine as a gift).

**Q: how many card fit**
A: The most I ever had in it, was when I didn't want to carry my wallet, 10-12 cards plus folded cash. And after that it was still able to carry less cards and nothing fell out!

**Q: does it fit the 5s?**
A: Yea it would definitely. I attached the card ninja to an ultra silk case so as not to stick it directly to the phone which I highly recommend but since the width of the 5 and 5s are virtually identical it would have no problem attaching to either just fine.
