My first thought when I saw the Bonez Black Graduated Double was that it looked like a stylized bishop in a large chess set. This was an impulse buy that I have come to really appreciate.
The Bonez is composed of very firm TPR which gives the toy quite a lot of give while maintaining a rigidity that makes thrusting this toy very pleasurable.
One end of the toy has a series of ridges that feel great being either slowly or more vigorously thrust inside the vagina. The other end of the toy is more simple being only a large knob and a gentle swelling before gracefully tapering to the middle bulge. The toy isn't overly girthy being only 4 3/4" in circumference at it's largest point. It is a fairly lengthy toy at 7 1/2 inches with approximately 6 1/2 inches being insertable depending on the side you use. When thrust vigorously it didn't cause any discomfort or bruising but it is very firm none-the-less so if you are very sensitive take care.

The toy feels as though it is hollow in some areas and solid in others. Just underneath the middle bulge the toy can be bent nearly in two, though it won't hold that shape. It has a seam that runs down the sides of the toy but it is soft and doesn't cause any sort of discomfort during use either with or without lube.
The Bonez Graduated Double can be rather effectively used as a kegel exerciser by adding some lube, whatever brand and style you prefer, and inserting the toy to the middle of the toy. Clench and release around the toy while either standing or by gently pulling on the toy. It's not a particularly weighty toy being around .2 lbs but it can deliver quite a vaginal workout.

This toy is easy to clean with warm water and mild soap but bear in mind that this is a TPR toy and it is porous. I have placed it in the top rack of my dishwasher without soap and it didn't ruin the toy. For complete protection you could cover the toy with a condom but unless you plan to share the toy, or use it anally, it's not really necessary.

I, personally, wouldn't use this toy as an insertable anal toy as it doesn't have a flared base and I have no intention of being the "butt" of an emergency room joke. It does have nice textures and with extreme care it could be used as long as it is covered with a condom. It would need some extreme care as the toy gets very slick with lube, perhaps as a partner toy it would work just fine.

The Bonez arrives in a clear plastic sleeve that is way larger than the toy. It is easy to open but not suitable for storing this toy. The toy is clearly visible but doesn't scream sex toy due to it's non-phallic shape. The paper insert says the name of the toy and has some black curlicues along with some basic instructions and information about the toy. No porn star photos or other garish decorations making this toy seem fairly classy and upscale.

Although this was an impulse buy it has made it to the top drawer of my bedside table. I usually prefer a vibrator but the feel, and textures on this toy are very exotic feeling. It cleans up so nicely that I can't find fault with it. Paired with a clitoral vibe it makes for a great play session either alone or with a partner.

This toy hasn't seen much use as a sex toy as I have to hide it from my son who believes it to be the best teething toy he's had the luxury of using! Apparently is is just the right consistency of chewy and rigid that it makes his gums feel amazing. I don't mention this to freak anyone out because my kids are not exposed to sex toys in use or in inapropriate ways. Monkey got ahold of this one while it was sitting in my room after being washed in the dishwasher. The reason I mention it is this has been chewed for hours and hasn't got a mark on it! Now that is what I call durability!
It has withstood kitten teeth and baby teeth so in terms of wear and tear this is top notch!
