As you can see from this image, it shows I can't purchase these event items from the Zen shop.
I have seen this issue before and it has to do with the fact the items are not supposed to be displayed until a future time. I suspect these are items for the Feast of the Lanterns event.
That being said, there are not current event items being displayed in the Events section of the Zen shop.

I think these items were for Chinese New Year. I said "were" because it is still Year of Pig.
The coming Chinese New year is Year of Rat.
Hence, these 2 items are not exactly match to the "theme".
Also, I still am unable to buy the two items in my OP
