Colibri has a unique book covering system that can protect and preserve any type of book whether it is soft covered or hard covered (with or without dust jackets). The process only takes 20 seconds and is completely automatic - done by the touch of your finger or with a foot pedal. There are no tapes, glues, scissors, rollers or adhesives needed for the application. Our covers do not adhere to the book or dust jacket in any manner and can be easily replaced without damaging the actual book. Colibri also has a line of document pouches that can be used for archiving purposes. There are only 3 size covers that can be form fit to any size book.
