Have you heard of this word "マジック"?
マジック has two meanings in Japanese.
One is "magic" and the other is "a permanent marker".
Most Japanese people use this as a general term for a permanent marker.
Actually, this topic is similar to the post that I wrote about a glue.

"マジック" comes from the name of product "マジックインキ", which made by Teranishi Chemical Industry Co., Ltd.
A general term for a permanent marker is "油性ペン"or "油性マーカー" in Japanese, but almost all Japanese people use this word "マジック" as a general term for a permanent marker.
I work in a laboratory and use a permanent marker almost every day, so I often hear "マジック持ってます？/マジック貸してください", but our section has the one made by Teranishi Chemical Industry Co., Ltd. lol
