This beautiful, erotic, crystal-like glass probe by WHK GmbH is a wonderful toy to own - great for anal or vaginal play. It comes in a simple cardboard box with a Styrofoam inlay, which I threw away. I stored it in a satin bag to protect it better. This clear glass ripple probe has six smooth, rounded bumps that gently graduate in size, making it easy for insertion.

This glass probe's ripples give you amazing stimulation and unique sensations; the flared base works great as a handle for use during play with or without your partner. Pair this toy up with a vibrator and you be saying words you've never heard yourself say before - just don't let the two toys hit, or it will feel and sound weird. This glass toy is temperature-sensitive, so you will be able to feel it warm up naturally to your body temperature with use. You can also increase and decrease the temperature sensation by dipping the glass probe into ice cold or steamy hot water before use.

You will be able to use your lube of choice with this product, but the probe gets slippery when wet, so it can be hard to hold on to. And if you or your lover gets carried away, I suggest you slow down, because you can hurt yourself or your lover. Nothing kills the mood like "Owww... stop!" So, word of advice: do not thrust as hard as you would with a non-glass product.

In addition to this sweet number, this glass is break resistant and hypoallergenic. It is easy to clean up; just wash in warm to hot water and soap or use your favorite toy cleaner. To make sure it is sterilized, it can be boiled or you can place it in the dishwasher. It is also microwave-safe and bleachable.

This is one of my favorite anal toys. The ridges from the bulbs give wonderful sensation. This was my first glass toy. You do want to be careful when heating up or cooling down this toy, so that you do not over heat or over cool it. Other than that, I love it.
