Rilakkuma original ballpoint pens, a set of 7. Unused, not for sale. These are novelty items from Mitsui Sumitomo Primary Life Insurance. The ballpoint pen ink color is black. Ballpoint pen length is approximately 14cm, 0.7mm. Very easy to write with. I am selling these as I have no opportunity to use them and am decluttering. Feel free to comment. Thank you.
