Hi everyone! I could really use some help......what should I use to label the backs of my photos? The Zig Millennium photo-safe, acid-free, archival quality pen that I purchased takes forever to dry (my photos have been sitting for over 20 minutes and still smudge!). What could I use that would be safe and dry quickly, so that I can quickly get these photos scanned and into albums? Thanks in advance for any help!!!
