Liquid proof secret compartment keychain?

[Dolphinjon]

I made a few secret compartment keychains out of Olivewood for a show I did this past weekend at the seminary I graduated from. I've had several people ask of they will hold oil. I've tested one with water and it seems to hold in the short term thanks to the o-ring, but I'm not sure of I can trust it. Does anyone know if it can safely hold liquids?

I forgot to add that it is the PSI secret compartment keychain.

I have made similar using the perfume vial kit. It was from CSUSA. They seem to hold oil with no problem.
