I recently got a fountain pen after having lost one many years ago. (A noodlers Konrad, go flex!) I’m using it often in my planner, which also has a lot of washi tape marking appointments. So far the few inks I’ve tested seem to not like washi tape as a surface to be written on. What inks work on washi tape?
Shana, I went to my planner-and-washi-tape experts, AKA my secret society of enablers, for some information. First thing I discovered is that washi is a word that gets used by a lot of tape sellers to describe a wide variety of paper tapes, some more papery than others and others more shiny. The original paper tape from Japan, MT stands for “masking tape” and actually, the term “washi” refers to a specific type of paper made in Japan. So technically, the tapes we use in our planners is paper tape or masking tape.
I asked my pals if they’d had any good experiences with tape and fountain pens and, with the differences in tape shininess, your results may vary from theirs. In field tests, all my secret society testers agreed that, while they could theoretically get some fountain pen and rollerball ink to adhere to washi tape, it tended to bead up and take way too long to dry to be useful. Most recommended that if you wanted to write on the tape itself, to use a permanent pen like Sharpie Extra Fine Permanent markers, Staedtler Lumocolor permanent markers, Stabilo Write4all permanent or American Crafts Slick Writers. The testers also suggested that ballpoint pens and gel pens do as well, but the gel pen needed a lot of drying time. One tester had some luck with 6B, 7B or 8B pencil but a pencil that soft may have the tendency to smear.
You may want to look for some plain paper stickers as an alternative to washi tape to use in your planner if you want to use them for appointment notations and write on them. Particularly Flex nibs will be a particular challenge since they lay down a lot of ink in regards to dry time as well. Quick drying inks might help like Private Reserve’s Fast-Dry line or Noodler’s Bernake series.
So, the short answer is no. Fountain pens and washi tape are not the best of friends. Best of luck in finding the perfect pairing.
