Depending on the price. If it's below 30 dollars I'd buy it.
If it's above 30, I would have ordered some online from a bonsai nursery.
Junipers are fun and itoigawa is a pretty fast grower. Kishu not that fast, but still fun to play with.
The one you have looks like it has a fat trunk, that can be a challenge for smaller material because they're harder to bend. The plus side is that there's less waiting for it to thicken up.
In the first year my own cuttings went from pencil-lead thickness to chopstick thickness, the next year from chopstick to thumb thickness. Basically doubled every year.
If yours were mine, I would strategically wire it this year while keeping all foliage, and strategically prune and repot the next year.
