I’ve been using my Spiral Bible for about a month now and I love it! I can highlight and annotate, map verses or jot down questions. It lays flat and is very ‘functional.’ Also very pleased that, after using everyday for a few weeks, it still looks nice… the pages are still nice and flat even after written on or highlighted on and the corners aren’t curling. The spiral binding is made of some kind of plastic that holds its shape well too and doesn’t get all bent up and wonky. Highly recommend!!
