These textured silicone balls are great for exercising your kegels, wearing during masturbation or inserting vaginally during anal sex. I really like this product, but I found the dual balls to be too long and a bit irritating for regular wear, although the girth is fine. I wound up cutting mine in half and wearing only one, which has helped. If you're concerned about them being too big, I'd suggest buying the Uno instead (or both types using the deal to see which works better for you!)
