Description

Material: This product consists of 5 metal balls, plastic brackets, and plastic bases. The rope for hanging the ball is made of thick and wear-resistant nylon rope to prevent breakage. The reinforced assembly design ensures additional stability, making it capable of withstanding daily games and long-term displays. Easy to Observe Clearly: The unique design minimizes air resistance, allowing Newton's cradle balance ball to swing continuously for approximately 10 to 20 seconds. This extended duration allows us enough time to observe the motion of the Newton cradle balance ball, making it perfect for hands-on learning of physics or simply enjoying the enchanting sport.

It is also a soothing desk toy for office workers to relax and unwind on busy days. It can also be used as a decoration to add a modern touch to home shelves, office desks, or classroom corners. Easy to Assembly: When installing this product, no tools are needed. Just align the bracket with the base, connect the pre strung balls, and finally fix them.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for UOUVOSTA products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
