Feint Ruled Wirebound Triplicate Book 102x127mm. The Q-Connect Spiral Duplicate Book features 100 sets of paper and two carbonless copy sheets with sequential numbering on each sheet for easier organisation, and an index card that can be moved to shield each set of pages. The top sheet is perforated so you can pull it out and retain a duplicate in the book for future reference, and it is spiral bound, allowing the pages lie flat for ease of writing.
