Rockitbot's Nerd Herder wallet has made me squee with glee! I've actually ordered this product (and even asked for some alterations) simply because it's just.. well.. cool.
This thing can pretty much hold all the little things you drag around with you. Phone, credit card, ID's, SD cards, headphones... all sorts O stuffs! Rockitbot was more than happy to make a few little adjustments for me.. I wanted a wrist strap, I wanted a small snappy thing to keep my phone in place.. No problem!
The incredible amount of choice you have in fabrics will kinda make you go Omg! too.
For $28.00, this is definitely a budget friendly must have.
