Yes, absolutely!
All book and paper styles are perfect to write on!
For our heirloom albums, Sakura Micron pens and standard Sharpies (not the pen) work great, and we really love Slick Writers. Just make sure you use a permanent marker, not a pen.
For Press-print albums, we suggest a standard pen that uses thick ink, not ink with water. We recommend a Bic pen!
