Giving up Edith's suitcase

I'm on the latest landmark and have seen that one of the items required to complete it is Edith's suitcase.

If I use it up, will that affect any of the rest of the gameplay? Are the items from the suitcase included in upgrading landmarks or anything?

As someone who isn't a fan of the suitcase, getting rid of it feels too good to be true 😂 I could use my cameras for other things!
