The Cortina Collection of 2 innovative products was developed to make it easy to put together a small, gorgeous album in no time. The details make the design. The Cortina cover is constructed using twin boards wrapped in Kolo's trademark book cloth in striking color combinations. The Cortina Lux features a sewn-spine construction, while the Cortina 2-Up features a plain spine for contrast. Note: Refills are not available for these albums.
