The Body Part Keychain from SillyAssToys (aptly named) can be purchased for $4.95 featuring noses, ears or tongues. And this is not just a body part, it is a pierced body part. Having a nose on your keychain is not odd enough, it has to be pierced.
The best line from the listing is, “Body Parts Keychain is recommended for kids ages 8 and up”. How many 8 year olds need a keychain? I also might reword it to say it is safe for an 8 year old, recommended is a bit strong for anyone.
