Zebra Mildliner highlighters feature unique pastel colours which make them one of the best bullet journal pens. The colours of the Zebra Mildliner pens are gentler than ordinary highlighters so they show softer colours on your bullet journal than ordinary highlighters. The Zebra Mildliner highlighters also feature water-based ink and a double-sided tip design — a standard chisel tip on one end for normal highlighting and a fine bullet tip on the other for underlining and writing notes. As the culture of "Bullet Journaling" in Japan spread to the world, it becomes the best highlighter of making journal decorations.
