Unbreakable Rubber

Material: Constructed from high-quality polypropylene (PP) fiber, often marketed as "unbreakable rubber" because the outer shell is designed to flex rather than crack under pressure. Mobility: Equipped with 360° easy-glide spinner wheels (often double-row "mute" wheels) for smooth multi-directional movement. Handling: Includes a telescopic handle system that locks at multiple levels to accommodate different user heights. Security: Most sets feature a secure zipper closure frame and may include a built-in lock system
