A friend of mine had the Japanese erasers when I was a lad waaaaay back in elementary school (back when vintage Wackys were brand new). He was Japanese and his father would bring them to him now and then to add to his collection.
I remember they not only had these cool, completely un-eraser like texture -- and were super colorful and detailed -- but they also
smelled amazing! Almost edible! This almost tranquilizing sweet smell that was like no other.
Dang, I remember the Frito stuff! I even recall when they got rid of the Frito Bandito. Sad day.
I also recall another pencil-related fad when I was in elementary school. They weren't erasers but did stick on the end of pencils. They were little fruits and vegetable characters you could buy at the local Longs or Rexall Drug stores. They came in multi packs but some of these guys were much more rare than others and I recall people showing them off in the tanned bark playgrounds. Was always neat when someone had a new one no one else had ever seen. I seem to recall a coconut one that was especially cool. I had a banana guy that looked strangely like Mr. Spock. Man, I've got to find whatever remains of this stuff one of these days!
