It seems to be a makeup brand from AEON. These are character-themed colorful ballpoint pens with black ink. There are five pens in a set, each featuring a cute character: Gura (cat), Muu (panda), View (bird), Ti (frog), and Kuu (bear). They are new, unused, and unopened. The brand is JETSTREAM, so the refills can be replaced when the ink runs out. Thank you for looking.
