I am very happy with this art markers. I purchased this for my bullet journaling. These are very comparable to the more expensive brand's dual tips markers that we also own. The difference that I noticed between the two are consistency of brush softness and delicate colors. However, these are pretty subtle and I would choose this one over the well known brand plus I get wider variety of colors for a fraction of price. There are some variance between the softness of the brush tips between the colors with this product (some are softer than the others), but I can easily adjust my writing to accommodate the difference.
I include one of my family member's hand lettering photo because I like hers better.
