Anything freeze dried should last for decades as long as it is properly stored and handled meaning absolute minimum exposure to moisture and remaining as air tight as possible. Moisture is the enemy here.
I'd just put them in a decent jar (if they don't already come in one. If not, a mason or a ball jar will work great) and call it good and try not to use wet fingers to remove anything from the jar.
