This full zip closure opens all the way up for easy access to your cash, coins and credit cards. It is large enough to also hold your cell phone inside when zipped closed. As with all of the purse products we make, this cell wallet is also lined with the RFID fabric between the wool and the lining. RFID fabric is a specialized engineered fabric that BLOCKS the thieves from scanning and getting other information in your credit card chips. And if your cell phone is inside, it helps protect that too.
