FI's longtime friend (from childhood) just graduated college. Everyone is super proud of her (first in her fam) etc and we are proud too

We missed her grad party (a huge 'kegger' type thing with a DJ etc- no thanks lol) but we want her to know we are happy/proud etc. What's an appropriate gift to send with a card? I was thinking gift card- but the amount we'd be able to budget is only like $20 and that seems low for a college graduate gift. We can ship stuff through FI's work at no charge so my next thought was a cute booze/glass set or something. I'm only a few years older than her but I know graduation is/was a huge deal for me and I want her to know it's no small task and even though we missed the party we are so happy for her. Any ideas on a gift that is college grad appropriate in the $20 range (I know it isn't much and wish we could spend more

)?
Re: NSAHMR- Grad Gift?
I got a large cooler as a graduation present once. I still use it, 20 years later. It is a handy thing to have. I don't think it would be much more than $20.
The book, "the places you'll go" is a fun token gift. Otherwise, I would probably do a gift card and call it a day. I tend to way over think these things. People appreciate the thought.
