Buyer benefits
Built to become a sellable range.
The value is not one generic claim. It is the combination of a differentiated soft-body format, selectable weights, private-label presentation and direct production coordination.
Plan several price and weight points
Multiple nominal weights let a buyer build an entry-to-heavy range instead of depending on a single hero SKU.
Align color, marking and packaging
Standard directions support quicker planning, while custom color, product marking and pack presentation can be quoted for larger programs.
Production managed at source
In-house production and capacity of up to 2,000 pieces per day support sample approval, scheduled orders and repeat-range planning.
Capacity and customization depend on the approved weight mix, color, marking, packaging and production schedule.
Confirmed construction
A product program built at source.
WENKU produces the PVC outer shell and fills each unit with iron sand. The printed weight is the nominal finished-product weight. Standard colors support faster planning; custom color, marking and packaging are quoted against order volume.

Market
Destination, sales channel, target date and required documents.
PVC describes the shell material; it does not by itself substantiate an environmental claim. Do not describe the product as injury-proof, completely safe, silent or certified floor-safe without defined test evidence. Final weight tolerance, warnings, claims and destination-market requirements are confirmed by SKU.
