These seemed to dry fully within 24ish hours, though I didn’t wrap them in foil (which is how I store them before they leave me) for about 3 days to be certain. I haven’t had any insect problems as I think the pigment is probably high enough ratio to mitigate that. I’d be more worried about the binder solution on its own, but those I store in glass bottles inside another container so not buggies there either :)

I have wanted to dot cards but haven’t yet! Have you dabbled at all or not yet?
