Resultado genial. La única pega que traspasa la hoja.
The pens bleed badly through any paper!! I don't recommend this for bullet journaling or scrapbooking, where you don't want the ink to sleep unto the next page. They're also very hard to write with and the ink doesn't flow well enough to write a full word. I tried using them for a long time in various angles but the flow stops mid-letter or mid-word. I was initially impressed by the cool dual ink effect but was sadly disappointed in the poor performance.
You need to be careful when using as they release a lot of ink and the normal folio calm the sheet but the effect is very nice
