Sorry tosee you tossed 20 bucks at that. Had you lived in my area, you could have somemthing likethat for free; I guess all bonsai growers have a bunch of cuttings sitting in a corner for one reason or another.
It is just a needle juniper. You can of course enjoy it -outside, if the guy told you it can be kept indoors he was plain lying to you-. But to make it into a true bonsai, you will need to wait a decade. It really ist just a young cutting. You can enjoy it, practice bonsai techniques on it. But don't expect it to miraculously to transfor into a tree like the one on the label, which I think I see in the background. That is a tree of 100+ years old.
Bonsai start more often than not, as a fairly big plant, which is reduced into bonsai size & styled as a miniature tree. One can grow them from seed an cutting, and it is a lot of fun. But it takes decades.
