Wax Paper... Cut a section large enough to cover the wrap area and use it when you put the cue in the case.... The rubber grip will grip the wax paper well enough to keep it from sticking in the case... Other option if that scares you is to take a silk tie if you can find a thin one and slot it so you can slide it over the butt... that way the end of the tie goes over the butt and you know it won't get stuck.....
