These small, clear photo corners are perfect for adhering valuable old photos to a scrapbook without compromising them at all. The photos never touch any adhesive, but are held securely. The corners are very small, and clear, which makes them less conspicuous, and lets the photo speak rather than the photo corners. They are archival safe, and acid and lignin free which makes me feel good about using them for precious old photographs.
The package says they can also be altered with alcohol markers, which I haven't tried, but that could be a fun way to decorate.
I am creating combination photo albums/scrapbooks with 35 years of photos as it would be impossible to scrapbook all of the photos. While I am using the really great We R Memorykeepers Page Protectors photo sleeves for the photos, the older photos are too small to stay securely in the 4x6 windows and I have to use cardstock to mount them onto. These photo corners are perfect to hold them on the cardstock.
