And from headphones, we move onto Pitaka's MagWallet which you can find at www.ipitaka.com
Having tried their MagHive before I was intrigued to see this product.
It is the world's first modular magnetic wallet that keeps all your daily essentials secure and accessible with a quick flick. It is made out of carbon fiber and has to be one of the lightest wallets out there. With that modular design, it is up to you how many cards you put in and how thick you want it to be as you can add more modules.
