Zebra pens contain preservatives and smell. The refill of the zebra pen is made of preservatives and some colored dyes. The taste will be pungent, like the smell of alcohol, but will not cause harm to the human body. The founder of Zebra Company, Tokumatsu Ishikawa, decided to name the trademark ZEBRA in 1914, hoping that all employees would unite as closely as zebras and work hard to produce stationery that is indispensable to the development of culture.
