From the Kickstarter page: “The NoPhone acts as a surrogate to any smart mobile device, enabling you to always have a rectangle of smooth, cold plastic to clutch without forgoing any potential engagement with your direct environment.”
I’ve been carrying around a deck of cards wherever I go, practicing sleights from Expert Card Technique. I find that I’m able to have a conversation while practicing with the cards, just as knitters are able to converse while knitting. I recommend a deck of playing cards over the NoPhone.
