drCase - the dodgeball

Item #: Scp-XXXX
Object class: Safe
Special containment procedures: The object, due to its safe nature, is to be kept at all times in site-15.18 within a standard box of cardboard, clearly labelled about its content, so as to make its transportation easier.
Anyone with at least level 1 clearance can read about the item, though experiments are to be approved from personnel of level 2 or higher on site.
Scp-XXXX will not react, as empirically proven so far, with any known inanimate object, hence containers of different nature are allowed. No guarding is needed.
Description: Scp-XXXX is a standard dodgeball that appears similar to the ones commonly used in the popular game.
Its dimensions, though, vary under no manipulation of any kind from 13cm to 22cm of diameter, apparently following the rules of the National Dodgeball League (NDL). How it follows said rules or operates said changes remains unknown.
Addendum XXXX.1: Tests conducted with mechanical arms or robots show no reactions from Scp-XXXX. Further examinations will be made if necessary.
