To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought these because of the price and the extra fine tip. I planned to use them in art journals to add fine details. They are not as opaque as I'd like (not nearly as opaque as Posca). They also tend to leave tiny little splatters along the paper as I use them. I've only tried them on sketchbook paper so far, so a smoother paper may work better. I also have not tried them on the multiple surfaces they are designed for, so they may work much better on something other than paper.
Keep on shaking! The tips clog no matter how well you care for them. The paint thins quickly and whatever you are covering may show thru before your line is finished... No matter how well youvè shaken the pen! Otherwise a pretty good beginnrrs tool.
I like the smoothness of the ink, but when you shake the pen and press down it doesn’t always come out of the tip easily. It also doesn’t always show up as white completely (say, if I color over a spot I colored with blue colored pencil) ; it sometime blends more with the other color.
Honestly though, it’s the best product I could find compared with stores in my area.
