The new Dyalog system by Dylusions is an easy and colourful way to organise your life. Each cover features original art work by Dyan Reaveley and is 5.875” x 8.75” (approximately 15cm x 23cm). The insert books are available separately in a variety of designs. There are two interior elastic bands to keep your elements secure with other elastic bands also available to add more inserts, while allowing the ability to change books easily. The outside elastic bands help keep the cover closed for security while out and about.
