I don’t bother wasting money on other pens to write with now. For lists, notes, letters, cards, planners- anything I want colour and the smoothest pen which will make my writing look better, I solely go for Uni-Ball One Gel pens now I’ve found them. They don’t smudge when I write on any paper, because they’re already dry by the time my hand goes over them. They don’t do blobs of ink.
Smooth. Neater handwriting. Great for drawing. Different nib widths. Wide range of colours. Dries faster than I can smudge. Best pens I’ve found.
Save your money. Buy these. Ignore the other kinds of pens.
