LOS ANGELES – Live-cam performers employ a variety of props during their shows. According to one novelty manufacturer, its new product has become such a hit with some cam girls that the company wants to give others an opportunity to try the item.

The Magic Ball is Pink Diamond69’s sole product. Already popular with performers including Leia Down, Kissa Sins and Tara Holiday, the Magic Ball is based on what in the mainstream are called yoga balls or exercise balls. In the mainstream, the item is used to improve core strength and balance. For the adult market, the addition of a dildo and/or butt plug makes the balls more fun.

Through Nov. 30, Pink Diamond69 is offering the Magic Ball at $20 off the normal retail price of $69.99. Shipping is free within the U.S.; buyers in other countries pay a flat fee. The special price is limited to one ball per customer. In order to receive the price reduction, buyers must email Sharon C. to confirm their status as a webcam performer.

“We like to help out the cam girls, since they’ve done so much to promote our products,” Sharon C., who owns the company, said. “Every cam girl should own a Magic Ball, and now they can at an unbelievable price. We have a lot of gay guys who love it, too. They can also take advantage of the special pricing.”

Affiliates, too, can benefit from the sale: They will continue to receive a $10 commission per ball sold.
