Legami Erasable Gel Pens

Legami makes the cutest erasable gel pens. Maybe the cutest gel pens. Which would probably make them the cutest pens. Legami aren't Japanese, but these would definitely fit the Japanese 'Kawaii' style. Cute bees, cute hippos, cute pandas, cute piggies, and so many more.

And if you're remembering erasable pens of old (yes, some of us are old too!), don't worry, things have changed. These use heat-reactive ink, with friction causing the heat and turning the ink clear. The result is that they're super-smooth gel pens, but you just happen to be able to erase the ink. And if you accidentally iron your notes and bulk-erase them? No problem, put them in the freezer, and the reaction reverses, bringing them back, a bit faded, but readable again.
