Sendros Desktop Punching Bag Black, Compact Desk Stress Reliever with Silicone Suction and Quick Rebound

The Sendros Desktop Punching Bag is a compact desk-mounted stress reliever that attaches with a silicone suction cup and rebounds quickly for short, satisfying hits.

This small, portable punching bag is designed for adults who want a fast, unobtrusive way to release tension at a desk, gaming station, or home workspace. It combines a high-grip silicone suction base with a soft PU rubber striking sphere and an 82B carbon steel spring core so the ball returns promptly after each tap. Assembly is tool-free and takes a minute, making it easy to move between surfaces and share among coworkers or family members.

How strong is the suction and where does it stick best?

The upgraded silicone suction cup offers much stronger adhesion than typical rubber cups, rated up to 100 pounds on ideal surfaces. It works best on clean, smooth, nonporous surfaces like finished desks, glass, or metal; uneven or textured tops will reduce hold and are not recommended.

• Max suction force up to 100 pounds on smooth surfaces
• Best on glass, polished wood, metal, and sealed countertops
• Requires a clean, dry area for optimal grip
• Not intended for heavy or violent impacts

What materials and construction deliver the rebound?

The striking sphere is made from soft, impact-resistant PU rubber with a sponge outer layer for comfort and pinch protection. The return mechanism uses an 82B carbon steel spring inside a central lever, providing a fast, consistent rebound without harsh shock.

• Soft PU rubber ball for forgiving hits
• Sponge outer layer reduces pinch and noise
• 82B carbon steel spring for quick rebound
• ABS base and silicone valve for durability and grip

How do I set it up and maintain the desk punching bag?

Setup is simple and tool-free: inflate the sphere with the included tube, connect the levers and base, and press the suction cup onto a clean, flat surface. Check that joints are firmly connected before use and clean both the suction cup and surface periodically for best adhesion.

• Inflate sphere using included tube
• Assemble lever and attach to suction base
• Press firmly onto a clean, flat surface to secure
• Wipe base and surface to maintain suction strength
