Is ngc box moisture-proof?

The Ngc box is moisture-proof. Ngc-grade coins do not need anti-oxidation treatment, and the box is well sealed. The box of rating coins is hard material, not a good vacuum material, but a good protective material, so rating coins are not vacuum boxes. But a kind of packing box, which can block some air.

Some sealed packages are isolated from the air, and most of them are sealed. Like plastic on the market, it looks very tight, but in fact air will still enter and be invisible to the naked eye.
