PU Light Bulb Stress Toy

This light bulb stress toy is made from soft PU foam with a tall spiral coil design and an easy-to-grip surface. The flexible foam compresses under hand pressure and gradually returns to its original shape after release for repeated squeezing. Raised ridges, a molded screw base, and one-piece construction add tactile detail while maintaining the familiar light bulb profile. Its lightweight design is easy to handle and suitable for desks, classrooms, electrical training, construction programs, and related educational activities.
