Put simply, the CO3 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 CO3 balls differ only in weight. The lightest blue version, at 2oz/60g 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 ball a breeze, you can move on to the medium pink version at 2.9oz/82.2g. The red ball is the heaviest, at 3.7oz/104.9g, 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 CO3 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 favourite water based lubricant, but please keep it away from silicone lubes and other silicone toys
*Balls measure 5" (12.6cm) in total length and they're about 1.6" (4cm) insertable. Each ball is approximately 1.55" (3.8cm) in diameter
