Ephemerabilia

Objects like groan tubes, bouncy balls and light-up wands you buy in novelty shops that seem great at the time but later you realise is just worthless shite.

Fred:...Why did I buy this Glowing Mickey Ears light up wand in Disneyworld again?
Lucas: Dude, I told you when you in the shop, that's totally just ephemerabilia.

Assorted objects that people tend to accumulate, like receipts and ticket stubs and tissues.

There was ephemeralia scattered all over the floor of her room.

ephemorabilia 

Items which usually have a short lifespan, or fleeting existence, but which become keepsakes. Different from souvenirs or memorabiliia (which usually have an intentional association with a place of origin, or an event) ephemorabilia was never intended as such.

Mary kept a cigar box full of quirky ephemorabilia from her travels: a vial full of snow, pressed leaves and flowers, the shed skin of a snake, ticket stubs, and gumball machine toys.
