Made of tempered glass, this plug is nonporous and sterilizable. It's also fairly weighty, more weighty than silicone, rubber, or other materials. Glass has no give to it whatsoever, and is firm as rock—take out a wine glass and feel it with your hands a bit, you will see its firmness. This is not a hollow glass plug; it's solid and has very few imperfections (the imperfections are only inside of the glass itself and cannot be felt internally or externally). Since it is so weighty, and because it does hold temperatures very well, I do not recommend people just starting anal play to use it. It's not something that's a starter toy, it's definitely for people well-versed anally.
Glass is always extremely smooth, even when there are bumps and ridges, and Soother is no exception. It can be rubbed on a person's skin before use for teasing, and inserted with little lube (use any of your favorite lubricants, as glass can be used with anything and becomes very slick with only a small amount). Since my Soother is a light pink color, translucent, it can be seen through and if touched a lot can acquire some fingerprints which are noticeable. Glass is also scent and tasteless, taking away the worry of this lovely piece making your home smell bad.
Soother, the bum plug, reminds me of Luxotiq's Hera dildo. It is smaller, however, and more curvaceous than Hera. Rather than being a thin, long piece of glass, Soother's bulges are rounder. The plug also has a ring that serves as a means to remove the plug and keep it in without letting it be sucked up and therefore irretrievable. Because of its design, this is the type of glass plug that makes a "popping" sound when it's inserted into a well-lubricated, ready bottom. It has two bulbs, the first inserted smaller than the second, and has a heavy weight to it.
Soother has an entry ball that's spherical with a diameter of 1", making it easy to insert in the anus and also very small. The smaller bulb tapers down to a 3/4" diameter at the neck, which is only about 3/8" in length. With a 1 1/2" diameter, the second bulb is certainly harder to insert than the first. There is no wiggle room between the first and the second, so know your limits (or push them). The total length of Soother is about 6 1/4", including the ring. The ring, which can be used for fingers to hold onto or for string to pull on, is an inch in diameter and 1 3/4" in length. Only an inch is allowed for fingers; I was able to fit one of mine comfortably.
Because the shape is so lovely, I found that it's also very good for vaginal use, like the Hera dildo. This is my first glass product, and I absolutely love it. It's weighty, but not enough to make it intimidating to someone who has never had glass before, and it's absolutely gorgeous. The ring used as a base makes the plug very comfortable to wear, as no edges dig into the bum cheeks at any time, and the curved body allows for smooth insertion. The ring also keeps Soother from being sucked into the anal canal.
I had originally used much too much lubricant with it that was a more watery substance and the plug was repeatedly slipping out because of that. After trying it out with a thicker lubricant, it did stay in very well, in any position. It was able to be worn while walking around, though I do not believe that it's good for keeping in for longer periods of time, because glass has the ability to bruise the anal canal, even if it's beautifully rounded like Soother.
Glass is very easy to clean, and it's also sterilizable, making it great for people who have multiple partners or who like to share with one partner (can be used for any couple where both partners enjoy anal plugs). You can boil glass to sterilize it, or wipe it down with a 10% bleach solution. I personally prefer boiling it, as I do not like putting it in either the washing machine or using bleach. After cleaning it in this way, store it. I do recommend, when taking it out for use, to give it a quick rinse with warm water.
Always keep Soother somewhere nice and safe, where it won't break and will not be exposed to extreme climate/temperature change. Generally, people like to keep glass products in well-padded places where they're sure it will not break; this is a very good idea in order to keep Soother safe and ready for use.
Soother comes in a box-like packaging that has a polyester (with a satin-like texture) inside and it closes by a magnet. The plug is tightly kept in place by both an elastic band and a little ribbon tie. It's very lovely, and I intend to keep it. Inside the box is a cotton, with suede-like finish, drawstring miniature bag that is good for keeping Soother pretty and smudge-free. On the back of the box, there are little bullets of information in a few different languages, telling how to keep Soother clean, how to store, and how to use for temperature play. They warn against putting Soother in the microwave (and they're right—do not ever put glass toys in the microwave).
Since I have never used glass, I've noticed that this glass plug does not retain scents of any type. Even a simple quick rinse removes any traces of fluids or scents, which is a great thing.
