I love the initial coolness while inserting and for a bit after insertion. They go in easily and stay in, unless extremely wet snd aroused. It is fun to wear them for a while and then laying them like eggs after getting yourself aroused. I used a vibrator on my clit for a while snd once I was horny enough, I pushed them out. They are good quality solid glass and completely smooth. They are a beautiful pink color and they look great when popping out. I create some videos popping them out and I will be making more videos with them. They do the job and look pretty in the process.
