Give a gift that’ll simplify your girlfriend’s life. The CardNinja is a soft fabric-based currency holder that attaches to the back of her smartphone and nixes the need to carry a separate wallet or purse.
The CardNinja is a fabric card and cash holder that attaches to your smartphone via a piece of double-sided adhesive on the back of the product. It’s just like a sticker, but leaves no messy residue upon removal. It is made of an incredibly durable custom spandex blend that can withstand the wear and tear of going in and out of your pocket — several thousand times. It also sticks to most smartphone cases, so long as the surface is flat. Check out this template file to make sure it will fit on your phone.
