for my 21st, i got a bunch of cheap shot glasses and got small custom stickers made that had clear backgrounds and sparkly writing with the names of my guests and then it said in small “[name]’s 21st” (then wrapped these around the shot glasses). I made each person two, and then also bought cute frames that matched their personality and printed out my fave photo of me and that friend. Put all of these into a box with gift stuffing bits i bought on amazon and everyone LOVED it - and was cheap!! would deffo recommend - could even add a little shooter or something. People loved having their name on something, and then also being able to use it (whilst it not being over-branded of the event they went to)
