This toy (which I re-named Wave) is ideal for fucking - alone, with partner(s), vaginally, and anally. Its gentle curve feels great on the G-spot, and I imagine it would be great on the P-spot too. If you're a fan of smooth textures, Pyrex glass toys like this one are delightful. It's a subtle pleasure, as the curve and girth are slight - but I was very pleased with the effect!

Also, glass is wonderful at different temperatures - cold or hot, it adapts quickly. Temperature play is quite fun, especially if one of you is blindfolded...

It is hard glass, and quite long, which calls for gentle self-exploration the first time around - it hits the cervix easily, which can hurt. When I began to play with it, the first thirty seconds or so were punctuated with tiny ouches, as I found the edges of its range & discovered the best angles for my own pleasure. I would recommend using this on your own before you use it with a partner.
As far as harness-play goes, the base is too small to stay in most O-rings, and the weight of the toy could make it hard to maneuver.

I have yet to try this toy anally, but I am very excited to do so! The base is flared just enough to make this toy safe for anal, and the length and texture (as well as the pronounced head) are very promising. Check back for the follow-up review!

Glass is by far one of my favorite materials, for its smooth texture and delicate beauty. With a little lube, it slides over skin like silk, with very little grab or friction. This is, in my personal opinion, a transportive experience... I am a huge fan of glass, for texture alone.

Otherwise, as you may expect, it is rock-hard, has a nice heft, and is both tasteless and odorless. As I mentioned earlier, such a solid toy means you have to be gentle with your delicate insides, but even first-time users like my lover (who was hesitant to use glass, as she imagined its rigidity would hurt) can quickly learn to maneuver it in very pleasant (and often orgasmic) ways.

Subtle and understated, this design WORKS. The head is just pronounced enough to have a teasing and, eventually, powerful effect. The curve's soft stroking is a slow build-up that eventually boils over.
It's long, at 7.5", so it can reach depths other dildos don't approach. It's also long enough that, at shallower depths, it provides a useful handle.

Its shaft is fairly thin, at 3.3" circumference, 1" diameter. This was actually very pleasant! I was surprised, as I tend to like larger girths, but the shaft tickled my insides and had them grasping for contact. This made my vagina start to contract more quickly, and led to a surprise orgasm!

The head definitely helped with this, as it is much more pronounced - 4.3" around, 1.3" across. The head itself feels just delightful, and the change in width makes a strong statement.
Lastly... it's just so pretty! When you turn it, the ripples wash over each other and seem to shimmer - like a psychedelic animation, or lights reflected off water.

The Wave is easy to hold on to (unlike the ones at the beach!), so is especially good for self-play. It does have a tendency to turn in your hand, though, as it's both hefty and, likely, wet & slippery. If you begin with it angling upward, for a G- or P-spot, it may rotate during use so the tip points down. This can feel good too, but if you are aiming specifically upward, you may want to try it with rear-entry so gravity can keep the tip where you want it.

Glass is completely solid and nonporous, making this a 10 out of 10 on that handy material safety chart. It is compatible with all types of lubes, and afterward you can clean it with soap and warm water, sex toy cleanser, or in a dishwasher. Wipe off water or let air dry, and then you can either store it in its soft drawstring bag, or upright on a (sturdy!) shelf for display.

The drawstring pouch that comes with this toy is useful, though more on the tacky side of cute. The faux-suede (polyester) outside is a bright purple, with a soft shine. The inner lining is a shiny pink satin (also polyester), and the drawstrings are soft, black rope twists. There isn't much padding, but the lining would likely be sufficient to dull any potentially fatal falls or blows.

To address the oft-repeated "but what if it chips?" fear - it won't. If you keep it in its bag, or really anywhere it won't fall, you'll be fine. Even if you drop it on a hard floor or object, Pyrex is a dense enough glass that it would break into large pieces - not into slivers or chips that would go somehow stealth until you painfully discover them. Not to worry!
