For distributors, brands, retailers, gyms and studio procurement. Single-unit retail orders are not supplied.
Buyer benefits
The value is not one generic claim. It is the combination of a differentiated soft-body format, selectable weights, private-label presentation and production coordination.
The moulded PVC body and iron-sand filling give brands a clearly different product format for home-fitness, studio and retail assortments.
Multiple nominal weights let a buyer build an entry-to-heavy range instead of depending on a single hero SKU.
Standard directions support quicker planning, while custom color, product marking and pack presentation can be quoted for larger programs.
WENKU manufacturing 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
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.
