Thud juggling balls and especially beanbags are the most common type of juggling props.
Juggling beanbags are normally constructed with an outer shell made from several pieces of vinyl, PVC or imitation leather and filled with millet, birdseed, sand or other materials designed to give the beanbag bulk.
Beanbags come in a variety of colours like White & Colour Thuds, Black & Colour Thuds, UV-Active Thuds, "Glow In The Dark" Thuds and lots more..
Thud Juggling balls are preferred by many jugglers because of their lack of bounce and roll when dropped, the ease with which they are caught and their reasonable price and availability.
Beanbags are generally found in sizes ranging from 2"-3" in diameter, though smaller beanbags with less filling in them are sometimes used by numbers jugglers, who require a smaller and lighter ball to facilitate throwing and catching many balls in the same hand.
