I was actually wondering why I didn't smell it until I rubbed and smelled with my fingers. I guess that is because it was already brewed so the usual aroma strength is gone.

It's amusing that you noticed the plastic container. I wonder if you would suggest using a paper box in the toilet?

Yes, the powder was dry when I tried to get a feel of it. A bit moistened, actually. So maybe it could have been dried and already started working to absorb moisture.
