The entire line of Climax Gems from Topco are wildly popular because of their attractive colors, clean packaging, modest price point, and dainty dimensions. The 5.75 Climax Gems Sapphire Swirl offers multi-speed vibrations and a flexible shaft with a flared tip and spiral ridges for extra sensation. The Sapphire Swirl is waterproof and uses two AAA batteries, sold separately.
