The BIC Intensity Dual Tip adult coloring felt pen expands your creative options in a single tool. It combines a flexible brush tip on one end with a fine tip on the other. With a simple change in pressure, you can use the brush tip to color in large areas in mere strokes or, with lighter pressure, create delicate calligraphy. Then spin this felt pen around to write precisely or color in smaller areas with the 0.7 mm fine point. Emphasize the important parts of your notes and decorate notebooks and journals with lettering, doodling and sketching. A water-based ink in a variety of pastel shades will make it all look beautiful.
