How long does Trader Joe's kimchi last in the fridge?

Could you please clarify for me, how long is it recommended to keep Trader Joe's kimchi in the refrigerator before it begins to lose its freshness or quality? I'm interested in understanding the shelf life and proper storage conditions to ensure I enjoy this product at its best. Additionally, are there any signs I should look out for that might indicate the kimchi is past its prime? I'd appreciate any insight you can provide on maintaining the deliciousness of this item.
