I have something similar. They are called Pals forms, and are a gel without a pouch. They claim to be able to take makeup to color them, but I have not yet tried. You can also cut them if they’re too wide (hanging out of the sides). Although I have never intentionally cut them, I have noticed a few cuts in the back. The forms are self healing with a bit of talcum powder. They are sleep safe too. For the first couple of years they did smell a bit like vanilla.
Besides being sleep safe, these forms are a darker color than most silicon forms. I have olive skin, and the pink of most forms looks obviously out of place. The Pals forms are slightly darker than my skin, but are a closer match than most. They are also priced just a little more than silicon forms, but not exorbitantly so.
Over a couple of years, the nipple has flattened out as well, but that’s OK. If I’m wearing a thin top I don’t always want the nipple sticking out.
Overall, I’m very happy with them.
