They are genuine Bonsai. They mass produce these little trees and they make great first Bonsai. This example is a great start. Not necessarily first rate but super to learn on before you get a 'real' Bonsai, half a century in age or more worth thousands of bucks...highly recommend a hands on class in Bonsai!
Bonsai is a PROCESS, never an end result. Yours looks like Ilex. Great foliage and needs thinning very soon. Water every day. Try to find bottled water or a friend's well water. There is also light, fertilizer, how much to prune off the top growth and then how much to prune from the roots to keep the top growth in balance with the roots. Start reading up on these guys as they are the ultimate test of a gardener. This is akin to adopting an animal friend for life? Constant vigilance yet so very rewarding.
Sign up for a class. The best are by Bonsai Masters (that seem to not speak English). The white gravel has got to go, grins! When I watered bonsai I would dunk the entire pot in a bucket of water and wait until the bubbles stopped. Sometimes that would be good enough for 2 days. Feel the weight of your pot and plant after soaking. It will feel markedly lighter when it needs to be soaked again. Your plant isn't meant to be watered from above at all...
