A toy forum may be a better place for this question: http://forum.rebelscum.com/forum.php

Rubber disintegrates, maybe wipe it down with some alcohol, but that may cause it to break down more.

Well I have not been able to get on that other forum but

Many people else where suggested alcohol fore sticky

Rubber. I try it and it works so far, after the alcohol I put some hot water on a old sock to wipe off all the alcohol then I wiped it dry. Then I put a new sock over the handle before putting it in the box. In the case that the Styrofoam packaging was to blame for the problem I did not want them to make contact.

Maybe this explains why the ESB Luke saber

grip is not the same as the ANH grip

Any way if there is not already one I may convert this to light saber discussion.
