Help expiration of unsealed SN container.

[greyback330]

hi
i got my SN today and it was sealed, i opened it to check it
and it was yellowish white crystalline material.
now it's unsealed how long will it be effective as it's not sealed(approximately).

As long as you keep it away from moisture it will be fine basically forever. The expiration date is more or less how long it stays pretty, but yellowing and clumping is normal.
