Colorclik Pen

A color click pen is a convenient, multi-ink pen that lets you switch between several colors (often 4, 6, or 10) with a simple push of a button or click mechanism, eliminating the need to carry multiple pens for color-coding notes, planners, or creative projects, featuring a single barrel with retractable ink cartridges for each color like black, blue, red, green, purple, and yellow, and often comes in fun designs
