American Express Credit Card Calculator. Condition is "Seller refurbished". Refurbished as in I've put a new battery to check it works, and it does. (Oh, and I've washed the wallet since I did the photos.) You've got to bear in mind that it's old, touch sensitivity is NOT its strong point, definitely more of a talking point than something to work your accounts out on. Dispatched with Royal Mail 2nd Class.
