NORTH HOLLYWOOD, Calif. – Adult novelty manufacturer Doc Johnson has re-released the Tower of Power™ cock rings in a fresh, new, black edition that comprises the company’s latest offering for extended erection and increased pleasure.

The Tower of Power is a set of six stretch-to-fit cock rings made from phthalate-free TPR. Since variety is the spice of sex life, couples have the choice of six distinct shapes intended to stimulate in six different ways. Designed to prolong an erection, the new rings come in an elegant yet sleek black color that any recipient will appreciate.

“The Tower of Power™ was originally released a few years back and was a huge success for us,” said Chad Braverman, director of product development and licensing. “Customers loved the variety this item offered and the low price point. After receiving many requests for a new color, we chose to release this chic black edition. It looks great and will drive a whole new market to this item.”
