A pack of 10 refills that fit our marking pens!
5 silver ink; these can be wiped off of leather and some vinyls. They cannot be removed from fabric.
5 heat sensitive refills in various colors; these hypothetically remove from fabric when an iron is applied. However, I've heard these can show back up in cold temps etc. So just be sure to do a test first or use it in places it won't be seen later.
