Eagle Neon

I rescued this Eagle Neon pencil from a thrift store a few months back. It has seen some better days. It has a petrified wedge cap eraser on top and it had a bit of ink spilled on the side... possibly from an old fountain pen stored alongside it. It has also lost a bit of it's bright neon pink color and the white undercoat of paint is showing through.  Despite its appearance, it still writes great. I'm currently doing a master's degree in mathematics and I did much of my work in my last course with this pencil. A great pencil makes doing homework a more pleasant experience.  

Neons are fairly rare. I only have one other example of this pencil... in equally well used condition. I've also never seen an advertisement for these pencils. I assume they are from the 1960s or so based on similar Eagle pencils like the "Eagle Rocket 88". The US version of this pencil came in yellow, green, and pink colors with a matching eraser.
