Key Stella II

The Stella II Kegel Ball Set is a vaginal ball set from Jopen’s Key line. Vaginal balls are designed to accompany Kegel exercises and increase blood flow.
Kegel exercises develop and strengthen your pelvic floor muscles, which can provide an overall better sexual experience for most women. Strong pelvic muscles give you a tighter grip on your partner during intercourse and can help you achieve stronger, or even multiple orgasms. Pelvic muscles can weaken with age or from childbirth and doing Kegel excises will help keep them in great shape.
Strengthening these muscles is also beneficial for women who suffer from weak bladders or incontinence.
Vaginal balls are designed to help you focus in on the muscles you’re trying to work and give you an object to squeeze your muscles around while also providing some resistance. These Kegel balls also have little weights inside them that roll around as you move and give extra rewarding stimulation as well as increased blood flow.
The set comes with a silicone harness and three interchangeable weights; one 30 gram weight and two 40 gram.
This toy should not be used anally because it’s very possibly for this item to get inserted too far and lost.
  • Material / Texture:

    The Stella I features a lovely smooth silicone, available in 3 vibrant colors. Silicone is 100% body safe and non-porous, and it will not harbor any harmful bacteria. This silicone is extremely smooth and has very little drag to it.
    The inner shell of the weighted balls is rigid and is most likely formed from ABS plastic, but they are fully covered with a silicone skin. There are also small emblems on each Kegel ball that identify the weight which are made out of ABS plastic. The silicone harness and removal cord is fairly sturdy and doesn’t stretch very much at all, which makes Stella very easy to remove, and doesn’t have me worrying about the cord snapping.

    Make sure to only use a water-based lube with this product because it’s made of silicone. Silicone-based lubes and silicone toys can potentially have a chemical reaction to each other which can ruin your toy.

    Stella II Measurements

    Stella II has an overall length of 6.25”, with the two duotone balls together measuring 3.75”. Each ball has a circumference of 4.5” and a diameter of 1 3/8”, and the retrieval cord is 2.5” long.

    The set comes with 3 weights; a 30 gram and two 40 gram. They are all the same size, but they each have a small dime sized emblem on them that have their weight printed on them so you can tell them apart. You can feel that the 30 gram weight has a smaller inner ball than the 40, and it has more room to roll around in the ball’s center and its movement is easier to feel than that of the 40 gram weights.

    Insertable length:
    4 3/4"
    1 1/2"
    9.5 oz
  • Performance:

    Select which two weights you would like to use and insert them into the harness. The weighted balls slide easily into the harness and have slight indentations which act as guides for centering them. It’s also possible to insert the individual balls without the harness and use them like classic Ben Wa balls.

    I found that Stella was easiest to insert while lying on my back, and a little bit of water-based lube made it more comfortable. It’s up to you how often you wear them, but the more you use them and do your Kegel exercises, the faster you’ll strengthen your muscles and start noticing a difference.

    I like to wear mine around the house for an extended period of time. They are very comfortable and provide sensation when I move around, and this reminds me to do my Kegel exercises.
    These vaginal balls also do increase blood flow and I notice an increase in arousal while I’m wearing them. They are great to wear during the day to get a bit warmed up and you can then incorporate their removal into foreplay with a partner.

    To remove Stella, simply pull on the removal cord which should hang slightly outside the vagina. You can relax your vaginal muscles and even push a little to make removal even easier.

    Special Features:
    • Premium
    • Travel kit
  • Care and Maintenance:

    Since the Stella II is made from silicone, and is very easy to keep clean. Please note that bodily fluids and lube residue can get between the harness and the weights, so make sure to remove the weights so you can fully clean both pieces. I prefer to take mine to the sink, spray it down with toy cleaner and they rinse it. You can also use soap and water, toy wipes, or you can use a 10% bleach solution to sterilize it.

  • Packaging:

    Stella II Box

    The Stella II comes in some nice packaging that is the same style as the rest of the other items in the Key line by Jopen. The box comes shrink wrapped, so you always know that your item is new and has never been opened. The outside is a slip cover that features an image of Stella II along with a lot of info about the product and its benefits. The slip cover comes off to reveal a black box that also has a lot of that same information.

    Stella II Set

    The front of the box is a flap that lifts up to reveal the set and extra weight nestled in black foam. There is a small satin ribbon at one end that you can pull to lift up the foam. Underneath are warranty info and instructions, along with a black satin drawstring storage pouch that measures 6.5” x 4”.

    The Stella II reminds of what you would get if you crossed the Je joue Ami Kegel set with Luna Beads. You have the all silicone design, but still have the different weights so you can customize your experience. In my opinion, it’s like having the best of both worlds.

    Ami and Stella retrieval cords

    The Stella’s retrieval cord is rounded and very comfortable to wear for an extended period of time. I find that the cord is nicely stimulating to the outer vagina and labia, and I haven’t felt and pinching or discomfort with them. I also really like that the cord doesn’t stretch very much, so they’re very easy to remove without having to tug very hard.
    Stella II’s size is unfortunately a little larger than I prefer, but may still work for a lot of women.
    The center of the harness that serves as a connector between the balls is a bit on the rigid side and takes a bit of pressure to bend it. The lack of bending makes this set feel a little bigger because it doesn’t conform to the body very much.

    Stella II Bending

    I would love it if Jopen made these vaginal balls available in smaller size, preferably with a thinner connector so they can bend and conform to the body a little more. But overall the quality of this set is really nice, and the colors are absolutely gorgeous.
