Kirarina Wink / Kirarina 2win Fluorescent Pen Set of 15, Perfect for Stationery. - Color: Multicolor - Brand: Kirarina Wink / Kirarina 2win / Beetle Tip - Type: Marker - Feature: Fluorescent Pen - Quantity: Set of 15 - Use: Stationery/Office Supplies The set of 3 in the case on the left was a gift from an insurance company. It has the insurance company's logo on it. I have not used them much. I checked that they write for this listing, but it is possible that the ink may not come out after delivery. They have been stored at home. I am waiting for purchase from those who understand this. Thank you for looking.
