Currently one of my favourite's toy. Perfect size for both Vaginal and Anal use, But as they are plastic the quality isn't the best. Fantastic product over all for the price.
I use this for pelvic muscle building and they're awesome. Easy to insert and remove. Feel comfy no hassle.
This balls are as I mentioned above good for a bit of fun. They're only silver plastic so as far as quality goes I wouldn't rate them that high. But they're fun to wear for a decent length of time if you feel like giving yourself a little thrill while doing the grocery shopping or maybe even like me, a TV interview....
