What exactly do you mean by "self healing"?
Are these buns like those 80's squishy stickers?
The buns are made with epoxy, it's not quite like those plastic poofy stickers from the 80s. The epoxy is slightly grippy and it rebounds from dents really well. For example, you could press your fingernail into it and the mark will disappear entirely after about 15 seconds.
Once they're assembled, they have a flying saucer shape which makes them really easy to pick up off the table, and their grippy nature makes them really easy to stack.
