This is an electric butterfly in a jar by Think Geek.
It comes in a few different types of butterflies, I think three - monarch, blue morpho and a yellow swallowtail. Just throw in batteries and you have a sweet decoration that isn’t imprisonment to a live animal. It responds to taps on the jar and loud sounds too.
This is a tiny robot, how cooooool.
So this is my latest buy and I wanted to share it while I wait for it in the mail hihi.
