Import Book Rings — Buy in Bulk from Supplier in China

These book rings are metal binding components offered by Aiven On Stationery Co., Ltd. in China. They are supplied in four standard diameters - 75 mm, 60 mm, 50 mm and 38 mm - to suit different document thicknesses. Each ring is forged from a durable metallic alloy that resists bending during repeated opening and closing. The simple lever mechanism allows quick insertion or removal of punched pages.

The rings are made from carbon‑steel blanks that are commonly zinc‑plated to improve corrosion resistance, a typical finish for office stationery hardware. Typical tensile strength for this grade is around 400 MPa, and the weight of a single 75 mm ring is about 20 g, which matches standard expectations for metal binding rings. Such specifications align with ISO‑based quality practices often applied in the stationery sector.

Customers such as schools, office supply distributors and craft retailers use these rings for document organization, report binding and DIY projects. Aiven On Stationery offers flexible order quantities, with packaging available in individual blister cards or paper boxes, and shipping terms including FOB and CIF as indicated in the listing. Buyers should confirm exact MOQ, payment conditions and any required certifications directly with the supplier before placing an order.
