I suppose you could tape the marker to it, but it won't fit in the holder. **Q: How do you get it to open. I received mine in the mail today and I can’t get it to spread apart** A: All you have to do is to simply spread it apart as needed. You may have to use a little pressure. One thing that could cause trouble is the little black locking nut on the top. Make sure it is loose first Just turn it counter-clockwise to loosen it. To fit a regular number 2 pencil in the holder, you may have to sand it down a little. **Q: Great Compass , but we’re missing the two set screws 😥** A: The carpenter's 12" compass I received lacked the locking and pencil retention screws necessary for its use. I e-mailed the Mr. Pen folks to request the screws early that evening. They responded via e-mail around three the next morning apologizing for the problem and stating that if I'd send them my Amazon order number they would be happy to send me a new compass. I did so and received notification that my order had shipped that same day. Two days later I received my new compass. No hassle and prompt, cheerful customer service make this a great outfit to do business with. And yes, the product was of great quality. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***Z on 17 October 2022* Es un buen producto, llegó tal cual el modelo mostrado en las fotos, material resitente y de calidad, quizá sea que el me me enviaron tenía un buen tiempo en stock y el material en algunas partes presenta unas pequeñas manchas negruzcas; es el único detalle, no afecta su funcionamiento.
