How to store natto and how to eat natto?

I never eat natto before. For first time I buy this [natto](https://www.japancentre.com/en/products/12713-yamada-foods-yawaraka-kotsubu-natto) and I want to make sure where I store them? Do I keep natto on freezer part?

Main problem is natto is not sticky and frozen, what should I do?
