1. Polyester Fiber Fill - used this for an audio project a while ago and just needed a little bit. It's clean and almost all of the 20oz is there. Can be used for similar projects (acoustic deadening) or to fill stuffed animals, pillows, etc
2. Green Bike Lock - has the one key it came with in it. Probably best for a kid's bike its not very versatile or sturdy.
3. Fellowes keyboard wrist rest - not used to my knowledge, found in storage, thought I'd offer it here before discarding it.
