Key Stella II Double Kegel Ball Set is a progressive pelvic floor training system from California Exotics featuring dual weighted balls in body-safe silicone. The changeable weights allow gradual intensity increases from 28g to 65g, supporting postpartum recovery and pelvic floor strengthening. The retrieval loop enables discreet daily wear for those seeking clinical-grade muscle engagement without complex equipment.
The Key Stella II operates by creating gentle resistance against the pelvic floor muscles during daily activity. As you move, the weighted balls shift slightly, prompting your pelvic floor to contract and stabilize them, building strength through natural engagement. This progressive resistance approach mirrors how muscles strengthen through consistent, gentle challenge rather than sudden intensity.
Body-safe silicone construction ensures the balls remain non-porous and hypoallergenic for sensitive internal use. The smooth surface resists bacterial growth and supports thorough cleaning between sessions. Those interested in expanding their pelvic health routine can explore our complete ben wa balls collection at Adultsmart for additional options.

After one week of consistent use with the lightest weight, progress to the 40g balls for increased resistance and deeper muscle engagement. Many people find that pairing kegel ball training with targeted pelvic floor exercises from our kegel balls guide creates faster strength gains than either approach alone. As strength improves over four to six weeks, advancing to the 65g weight provides ongoing challenge that prevents plateau in muscle development.
After each use, rinse the balls under warm running water and pat dry with a clean cloth. Store them in the provided storage pouch in a cool, dry location away from direct sunlight, which can degrade silicone over time. Do not expose the balls to extreme heat or harsh chemicals. Before first use and periodically during regular use, wash with warm water and mild soap, then allow to air dry completely.
Key Stella II uses medical-grade silicone that meets strict body-safety standards for internal use. The non-porous surface resists bacterial colonization and supports complete sanitization through simple washing. This material composition ensures long-term durability and maintains structural integrity through months of regular use without degradation or off-gassing.
This system suits people seeking clinical-grade pelvic floor strengthening without medical intervention or complex equipment. Those managing postpartum recovery, stress incontinence symptoms, or general pelvic health find the progressive weight system accommodates their changing strength levels. People who prefer discreet daily-wear training over scheduled exercise sessions appreciate the ability to strengthen muscles during routine activities while maintaining complete privacy and normalcy.
Many people experience pelvic floor weakness following childbirth, aging, or prolonged inactivity, yet feel uncertain whether medical intervention is necessary or whether home training can genuinely create measurable change. The Key Stella II's progressive weight system transforms this uncertainty by providing concrete evidence of advancing strength—moving from 28g to 40g to 65g represents tangible progression that mirrors actual muscle development. For those frustrated by vague pelvic floor advice or intimidated by clinical settings, knowing that consistent home training with proper resistance can rebuild core strength and reduce incontinence symptoms restores agency over their own recovery. The retrieval loop removes anxiety about internal retrieval, and the discreet design means strengthening happens invisibly during normal daily life rather than requiring dedicated exercise time.
Our independent testers evaluated insertion comfort, weight progression effectiveness, retrieval reliability, and material durability across eight weeks of regular use. The silicone surface remained smooth and non-irritating throughout testing, with no odor development or discoloration after repeated cleaning and storage cycles.
Testers reported noticeable strength improvements by week three when progressing to the 40g weight, with measurable differences in muscle control during everyday activities. The retrieval loop proved consistently reliable with no slipping or difficulty removing the balls after extended wear sessions. Individual results may vary based on anatomy, sensitivity, and usage consistency.
