These pumpkin spice almonds will last up to a week if kept stored in an airtight container at room temperature. You could also keep them stored in an airtight container in the fridge for up to 2 weeks for a slightly longer shelflife. Either option is completely fine but if you plan to give the nuts as gifts you'll want to leave them at room temperature and make them not too long before gifting them out so that the recipient has time to enjoy them too. I like to place some in mason jars and add nice ribbons and tags around the rim.
