The Bullet Stress Ball, a product by the brand Bullet, serves as an effective round stress reliever, crafted from PU foam. This versatile stress ball allows for bouncing, throwing, or squeezing to help manage stress levels. While each stress ball may slightly differ in density, color, size, and weight due to the molding process, they are devoid of half tones. Measuring approximately 6.3 centimeters in diameter, this stress ball is compact enough for easy handling yet substantial enough to provide a satisfying sensory experience.
