If you like your balls covered, this stretchy latex ball sheath will do the trick.  It has an upper cock base cover to hold the bag securely on the balls.

Rimba rubber items are packaged with a small amount of talcum powder to prevent the rubber from fusing to itself during storage, providing you with a longer lasting rubber item. The rubber shine products or a water (not oil!) based lubricant will quickly bring back it’s beautiful shine.
