For what I used it for (witch bottle display) they were great. Looks realistic. Didn't know the back was flat but if you throw it all together in a jar it's not noticeable. You are strong too. The only reason I gave 4 stars instead of 5 was that the little bits of pad got stuck to quite a few teeth so I had to brush every single tooth (except for a few that looked like decay) and it was quite a hassle . Although it can be easily removed with a swipe. I have very little patience so this probably won't be a problem for most people.
