Hi Regina,
That's a really interesting issue, I had thought the Micron pens were more long-term stable! I haven't had to label something directly in some time, but I've pulled some resources for other materials that might offer some other options:
C2C Marking and Labeling Collections Recording & Resources
- Includes a recording of the presentation given in 2015, and has an attachment with resources that might give some other materials
Ellen Carrlee's blog on labeling kits
- Ellen offers a different type of marker - the Zig Millenium pens - which may have a longer lasting black pigment in them.
What solvent are you using for the B72? Is it possible that it's just not fully evaporating off and impacting the legibility of the writing?
While we get some collections that have already been labelled, where I work has moved more towards either labelling the enclosure and including an image, or attaching a tag. Hopefully others out there will add their experiences as well!
All the best,
Liz
