Unfortunately, I now have a leather check book cover that is too small for check books! Not only is the pocket too small for a checkbook, but the plastic piece that goes behind the check you write (for duplicate checks) only fits about two-thirds of the way up the check. As a result, part of the note line and the "Payment" line are stuck. Use another provider if you don't want problems trying to use this thing. To the manufacturer: Measure seven times, cut once! Her measurements were off by about 1/4 inch. Yes very!
