Review on 36 Colors Dual Tip Brush Pens Fineliner Art Markers Set for Adult and Kids Coloring Books, Bullet Journal, Calligraphy - 0.4mm Fine Liners & Brush Tip Watercolor Pen - Hand Lettering, Note Taking - HO-36B by Carrie Spencer

My wife likes to color intricate black and white art pictures that were found in the form of a book. Often these pages feature animals or stained glass-like designs with sharp black lines. The parts needed for painting are a good test for pens. They work very well. The small tip is not too small, so too sharp or makes a fine line. The "Brush" side has a well shaped tip where you can apply the calligraphy technique, rolling from thick to thin lines. The best test was how the paint spreads and dries. Handles are fresh, without streaks or cracks. A big deal is painting large areas. Colors will not bleed after a reasonable drying time, such as before applying a second shade. These pens have proven to be perfect for this application, but actually have many more uses. Well made product with a wonderful range of colors. A better description would be - they are hilarious!
