Kegel or ben-wa balls have been around for a very long time (Japanese courtesans are thought to have used them in the 1600's, for instance), but today, kegel exercise is a well known practice in gynecological/obstetric circles. Kegels- the act of consciously and repeatedly flexing the pelvic floor muscles- can help tighten up the pelvic floor. A tighter pelvic floor leads to improved inner snugness, better control of continence after childbirth or surgery, the possibility of stronger, more intense orgasms and an overall happier vagina.
Put simply, the CO2 Balls provide a great-feeling object for the pelvic muscles to grip during kegels- you'll have to flex to hold 'em in place, and what do you know... there's your workout! Satisfyer has provided some illustrated exercise positions for you to try, but you can also simply stand or walk around the room.
Identical in shape, sexy silkiness and handy looped retrieval cord, the CO2 balls differ only in weight. The lightest blue version, at 2.2oz/62.4g is a perfect start point to kegel practice. It'll provide the least resistance and require the least amount of 'flex' to keep it in place. If you find the blue balls a breeze, you can move on to the medium pink set at 2.8oz/79.4. The red balls are the heaviest, at 3.4oz/96g, and will be a great incentive to work up to. Use a little water based lube for easy insertion.
In high quality body safe silicone (we'd expect nothing less!), the CO2 Balls clean easily using warm soapy water, but you you can also use a good toy care fluid/foam, if you like. This Satisfyer pleasure offering is compatible with any favorite water based lubricant, but please keep it away from silicone lubes and other silicone toys
*Balls measure 7" (17.6cm) in total length. Approximately 3.1" (7.9cm) insertable. Each ball is about 1.25" (3.2cm) in diameter
