I bought this a few years ago when it was released, but I never used it and kept it in storage. It's a collaboration product with Fujiya's Milky and Peko-chan. It has a variety of colored 0.5mm ballpoint pen refills and a smooth writing feel. - Brand: ZEBRA Sarasa - Model: SARASA NJK-0.5 - Colors: Black, Pink, Orange, Blue, Red - Size: 0.5mm Thank you for looking.
