I have a 35th Anniversary Confetti. She has been played with, and some of her glittery cutie-mark has come off. I guess I could reglitter it again, but glitter always seems destined to fall off sometime in the future through some sort of activity, even if it's really steadfast. So when more of her cutie-mark falls off, i'm thinking on painting it on again. (Basic fun ponies are made out of hard plastic. I'm not sure if they absorb ink as well as usual G1 ponies do, but I still think there could be one way out there that could stick).
What do you think would be a steadfast way I could paint/stain on her cutiemark?
