What do you mean it's not a bonsai? not that I don't believe you, I'm just not sure what you mean. Is this a sapling for a full size tree or something?
I think this is a question that is being answered about three times a day.
It's a juniper, young, untrained, not in any way different from any other juniper cutting. It's not even in a bonsai tray.
It's a young juniper, nothing else. If you let it grow, it will become a big juniper, not a bonsai. Bonsai is not a tree species, it's a collection of techniques to create minaturized, but realistic, trees.
With the right techniques your plant can become a bonsai. For a reasonable bonsai, that'll take about 15 years and requires study and practice. For a decent bonsai it will take longer, and for a real good one a few decades.
Selling this as bonsai is a scam.
