It's been so long since I last posted that my terrarium pendant (or should I say, pendants, since I unexpectedly received two) has already shown up in the mail. It's even tinier than I imagined:
The instructions say to give it one drop of water every two weeks--I guess I may need to invest in a dropper. (It does say that the excess can be soaked up with a Q-tip though.) Either way, I am quite pleased with my purchase.
