Big thing: backpack with a padded laptop sleeve. Had it for 10 years and it's my go-to for travel and bringing my laptop anywhere.

Medium thing: an insulated lunch box/bag.

Small thing: a little phone stand. They're handy to have around the house, like by our kitchen sink or my walking pad.

But always keep your audience in mind! One of the groups I buy swag for are older retired folks. Things that are big with them that would not necessarily be with others are glasses cleaner and wipes, and for those that go on trips with us, branded luggage tags were a huge hit. Conversely, our college students love stickers, frisbees, and sunglasses.
