Trackball Material

[HOOKBOT]

Does anyone know what the Trackball Bladder material is made of? We have students who are allergic to latex and we do not want to take any chances.

I am highly allergic to latex and I handled the bladder by putting it into the covering and I did not break out. No hives or respiratory issues. But if anyone if really concerned I suggest that he/she not touch the bladder. They should be ok once the covering is on.
