We currently only sell one size of foam filling. We have noticed that some of our customers prefer a smaller bulge and that the edges of the foam can be a bit hard which makes them itchy. We recommend cutting the foam with sharp scissors (to avoid fraying). Try to cut off layer by layer, to get the perfect fit of your liking.
In the photo you see the white foam normal size at the top, the black foam normal size in the middle and the black foam cut off at the bottom. The bulge will look smaller in your underwear after cutting as well.
