Aromatics don't age well, so if you are looking for improvement over time, you'll be disappointed. The toppings fade and there's so much Propylene Glycol in them that the tobacco won't evolve (or devolve, depending on your outlook) over time. The good news is that they are also well endowed with added stuff to stop fungal growth, so the tobacco won't turn moldy on you. If you are going to smoke in all in the next year or so, the tobacco will be just fine. Just keep moving it to smaller jars as you smoke it down.
