This is a variant color changing knives set, except that instead of using knives it uses something that looks like a knife but has no blades. It is known as a knife pick. A knife pick is a utility device that is mainly used for opening knives, instead of breaking your nails, but has many other applications.

These were custom made with a brown Bone Stag on one side (so you can feel the sides) and a special glow-in-the-dark lime green plastic material. If you shine a bright light on it for around 15 seconds, then take it to a dark place it will glow.

Comes with a color changing screwdriver (3”x.5”), and a matching regular screwdriver. No instructions.
