You're getting a polished 7cm stainles steel 410 cleaning ball, yellow color with a standard 7cm diameter, available in 20g, 30g, or 40g weights — that 410 grade gives it excellent rust resistnce up to 500°C, so it holds up better than most standard steel wool in wet kitchen or bath environments.
Basically, most professionel kitchens and commercial cleaning crews go with teh 30g or 40g for heavy grease and grime, while the 20g works fine for light daily maintenance on ceramic or glass; it's not ideal for abrasive stainless steel sinks if you're worried about micro-scratches, but for everyday soap scum and burnt-on food it outperforms scouring pads.

We pack each ball individually in OPP bags, so no contamination or tangling during shipping, and for US/EU/UK buyers we've got all basic import docs ready — COA, packing list, commercial invoice — though lead times are usually 20 days or so for custom orders (check before you schedule).
The surface is polished, which helps it glide better than the rough-cut alternatives, and our company can adjust the weight or diameter if your MOQ hits about 5000 units; that's a detail most first-time buyers don't think to ask, but it's worth knowing if you're planning volume.
We can produce as few as 500 pieces per weight variant, but standard MOQ is 1000 pieces total. If you need less, let us know and we'll see what we can do.
Yes, we can supply a material test report for the 410 stainless steel on request. It confirms the grade and rust resistance properties.
Standard lead time is 15-20 days after order confirmation. For larger volumes, we might need a few extra days to arrange production.
We can customize the weight per ball, but there's a small setup fee for the tooling adjustment. The 20g, 30g, and 40g options are our standard stock sizes.
Each ball is packed in an individual OPP bag, then we bundle them in cartons with bubble wrap. This keeps them clean and prevents scratches during transit.
