I’m looking for some face stamp items. I know a lot of CWs cake out, but I don’t remember what any of them are called.

What is a face stamp?

The custom wear items that leaves hearts or circles on your face

Like these? (I may be misunderstanding your description?)

Something like this?

A lot of those (if that's what you're looking for) have blush and/or eyeshadow attached, not just the symbols. But they're pretty easy to skim for if you go into the wardrobe and sort the face layer by Global, Show only CWs, added to site

There's also this non cw one

You might want to search for keywords like: Mark, Applique, Tattoo and Letter. Like the following examples:

Sorry everyone! I'm looking for something like that will only leaving a small heart on your cheek or under your eye

I have some of those :) I was just looking for something smaller, but I don't think that exists yet lol

the "punky" base eyes have a little black star under the left one. you can layer them under your worn eyes so only the star is visible. (there's also the rainbow sticker i'm wearing but i don't think that's the style you're looking for :P)
