This is a set of 4 pens: 2 Rilakkuma original 3-color ballpoint pens, 1 pink highlighter ballpoint pen, and 1 ballpoint pen, plus a Clickart pen. Unused, not for sale. This is a novelty item from Mitsui Sumitomo Primary Life. The 3 colors are black, red, and blue. The ballpoint pen ink color is black. Ballpoint pen length approx. 14cm, 0.7mm. They write very smoothly. I am selling these as I am decluttering and have no opportunity to use them. Feel free to leave comments. Thank you. I will be listing other items, so please take a look.
