Shelf life for Coffeemate packets?

My mom is having a party for her 60th birthday. She has a nearly full box of individual packets of Coffeemate powdered creamer that she bought for her 50th birthday. Are they still usable? She’s asking me and I don’t know. There isn’t a sell-by date on them.

According to the COFFEE-MATE FAQ

I’d buy some new creamer.

Thanks. I’ll let her know.
