This two-in-one fabric marker and eraser has a precision tip marker at one end and a wide slant eraser on the other. AND if you opt not to use the eraser, your marks will automatically disappear after 1-14 days. This allows you to mark your fabric as-needed and erase and fix any marking errors, but you don't need to spend the time erasing all of your marks or get your fabric wet because they will go away automatically (but you still have plenty of time to do what you need to do with them there!). Includes one self-erase marker.
