These are real dried rose petals, A 50g bag will be suitable to be divided up for five people as throwing confetti, these petals are best suited for throwing rather than decoration as they are slgihtly brown at the edges. The petals are around 1cm in diameter.

Many venues now specify no paper confetti since they do not want to have to try to clear it up afterwards so using completely natural confetti is a great option.
