PORTLAND, Ore. — Spartacus has released custom three-packs of elastomer cock rings. The manufacturer's exclusive elastomer rings broke sales records earlier in 2007, as droves of customers purchased the individual packs from retail stores, the company said.

A representative said the multipacks feature a custom clamshell as well as eye-catching, attractively branded package artwork.

"A multipack makes a much more substantial, versatile gift purchase than an individually packaged cock ring," Spartacus Sales and Marketing Manager Sean Christensen said. "Along the same lines, a multipack allows a man to buy a few rings and try them all."

Spartacus President Stephen Bergquist added, "We think there's a demand for cock ring three-packs that have different colors for different moods."

Spartacus elastomer cock ring three-packs are available in two color schemes: black/blue/clear and purple/blue/pink. The purple/blue/pink packs are marketed as edgy, flirty and flattering to any skin tone. The black/blue/clear color scheme is classically masculine.

Elastomer is a waterproof compound with no phthalates and no latex. A low pore count makes elastomer durable and easy to clean.
