Rubber band balls get ordered for three different reasons, and the specification changes each time: office desk supply, classroom and sports use, and decorative craft or event work. We hold 11 stock programmes, including 32mm and 38mm colorful balls, anti-aging heavy-duty balls for daily handling, and custom-color options for weddings and retail displays. Tell us the ball diameter, the band color mix you want, and whether it will be handled heavily — that determines the compound and winding tension we use.
