The ingenious Kolo refill system has whatever you need to display and store photos, artwork, and scrapbook pages. Kolo believes that people value their photographs as much as museums treasure their fine works of art, and is committed to making the finest quality archival photo preservation products.

What is archival? In the simplest sense, archival materials will resist decomposing, disintegrating, discoloring, or reacting to other materials over time. If an acidic material is in contact with photos or memorabilia, the acid can migrate, or transfer, from the acidic materials to the photos, causing them to deteriorate and discolor. Lignin, a naturally occurring acid substance in wood that breaks down over time, causes paper with lignin to become yellowed and brittle as it ages. Merely being “acid free” does not assure that a product is archival. All Kolo papers are made to a special recipe and rigorously tested to ensure that they are acid free (a pH of 7.0), lignin free, and stable over time — genuinely archival. Kolo archival page refills won’t harm treasured photographs and memorabilia.

Kolo protector pages are made of premium ultra clear polypropylene, a stable plastic product that is free of PVC (polyvinyl chloride), which can also harm photographs. Kolo protector pages simply slide right over album pages, protecting them from fingerprints and harmful environmental elements such as dust.

The Catalina 2-Up refill pages have plastic pockets that hold photos up to 4" × 6". There are 2 pockets on each side of the page, for a total of 4 photos per page.
