I bought my wife tickets for July 7th at Fenway and I want to surprise her with some extra little gifts the day of.

TLDR: Looking for suggestions for fun/useful gifts to surprise my wife with the day of the concert.

My wife absolutely busts her ass every day to keep our house a home and be an amazing mom to our 1yo daughter, and she rarely takes any time for herself without me pushing her to do so. Noah Kahan has by far been her favorite artist for the last few years, so I got her tickets for the July 7th concert at Fenway Park (she's from MA and we live in FL) so she could attend with her best friend. Her and her friend are over the moon excited and have been listening to the new album daily.

I was thinking I'd mail a box full of fun little gifts to their hotel ahead of time so that it'll be waiting in their room as a surprise. Fun things like a dozen cheap but cute bug antenna hairbands to wear and share with people or a pack of temporary tattoos of cute little bugs. Just a thoughtful little cherry on top that encourages them to have a great time.

Could anyone lend some other fun, useful, or clever gift ideas to throw into the box? Thanks in advance!
