I use my 6 key for my keys and car fob. I use the key pouch for cards, folded cash and cards. Love them both! I stuck my license and insurance card in the slot behind the key holder.
Bad idea - if you lose your key holder the finder will have your address and details on your license and the keys to let themselves in... please be safe - you never know who may pick it up or steal it... take care x
I use my 6 key holder and my key pouch (for coins and maybe a few bills) every day. If I'm really downsizing to a small bag, I take my car key out of the 6 key holder and only use the key pouch.
