Pro tip: Prevent AoSu center caps from popping off

[Dom]

This is my lovely wife's idea for use on any puzzle. Use fingernail polish on certain parts that sometimes come loose. This will add just a small layer so that it will fit more snugly inside the piece it fits into. Let it dry, then put it back together.

Thoughts?

Why not just glue them in though, I see no real reason why you'd need to take them off anyway...

In my opinion, the pieces should be able to come apart for cleaning. Dirt and grime gets caught up in there and it's nice to be able to take it all the way apart.
