These are great all-day ben wa balls. They have a nice, smooth, glassy finish that feels very good on the skin. I happen to like the dark color of the glass; it's very unobtrusive and pretty. They do clink loudly against each other, so it's good that they come with a nice soft bag with two compartments. If you put them in the carrying bag, you can carry them around without any telltale noises coming from your bag.

Size-wise, they're a nice size to get inside the vagina and and stay inside. Take a look at a ruler to get a sense, but they're bigger than Ping-Pong balls, but smaller than baseballs. They are big enough that you have to ease them in, and once they're inside and well-positioned, they won't fall out accidentally. You can squeeze them inside of you to get a nice glow, then relax and let them sit.

These are also good for temperature play. You can get them cold, and unlike metal, they don't get too cold.

As far as weight goes, they're on the lighter side; they have enough weight to feel them there, but not so much that you have to work at holding them in all day. Just slide them in, then do a good day's work or a good night's clubbing with a smile on your face. They made we wet in a very delicious, languid, laid-back way. Nothing over the top, nothing messy or intense, and that sort of thing definitely has its place. That's why I'm calling these all-day toys. I can still focus and be professional, it just makes me feel a constant, low-level hum of good. I can intensify that by clenching inside, then let go and just ride it for a while.

Cleaning is a cinch. Just wash them with regular soap and water, nothing special. Then, I dry them and store them in that convenient carrying bag.
