Table tennis rubbers can have the pimples (pips) facing outwards or inwards.
Pimpled rubber (pips) has the pimples facing outwards which means that the smooth side of the rubber is attached to the sponge. So you strike the ball with the pimpled surface.
Pimples out is available in two varieties:
- Short Pimples
Are suitable for players with a fast blocking or counter hitting game.
- Long Pimples

The majority of pimples out rubber have different thicknesses of sponge underneath them, but there are some which do not have any sponge at all underneath them, and these are referred to as “OX”.
