These "erasable" pens are my childhood dream come true. Finally, I can use pens for to-do lists and bullet journals as intended. And yes, I’ve been living under a rock and only just found out about "Frixion".

Useless trivia time: In Brazil there’s a famous dual-colour rubber called Mercur.
There's a popular myth that one side of the rubber can remove pen ink.
Well, it can't... But it's amazing at destroying paper.
Like many Brazilian kids from the 80s, I definitely put it to the test.
