How Are Pens Made In Factories?

I had to do a double take on these Languo gel Pens. This set has 213 pens with 207 colors as it has multiple silver, gold and white. I love the individual packs to keep the sets organized by color. These are great for detailing and patterns on coloring pages and adding highlights. And they are versatile enough to use on color by number pages! This is the largest set available right now of the 6mm size from Languo. I just can't get over how affordable they are! I think they’re great for writing,
