Stain vs No VOC Paint

[JennieLovesKisses]

I have some left over ebony stain from the enclosure project I'm working on which I used on the doors (the sections of exposed wood that I needed to cutout for the glass inserts.

Is it safe to use wood stain inside an enclosure with a sealant? What kind of sealant would work best for this?
or
Should I paint inside the enclosure instead with a No VOC paint?

I'd think stain is fine. Just let it dry thoroughly and then coat it with some polyurethane. Once that's all dried it shouldn't produce any harmful gas.
