Speed bumps!

This is an excellent anal probe. The handle makes it easy to grip and manipulate, and is big enough to be safe for anyone. It works well alone or can be handled by a partner if you prefer. I have tried it both ways and have been happy with the probe's performance solo and when I have someone else use it on me.
While the five bumps add a pleasing sensation, they are close enough together to slide easily in and out. Anyone new to anal toys or to glass, might find this handy since you can start off with just one or two bumps inserted and work your way up to the full length. The smooth texture makes it easy to use with a bit of lube and always use lube for anal penetration. Since this is glass, be careful with thrusting since it's hard enough to bruise sensitive anal tissues.

I am a huge fan of glass for many reasons. I love that it's so easy to clean and care for. I love the texture, rigidity, and it's just really pretty too. Since it is so hard, glass can feel bigger than a soft toy of the same size. This can be intimidating for beginners, causing some people to not like it for just that reason. I have found that I love the solidity and weight that glass offers. It's also safe to use with any lube you like. It won't pick up any smells, and has none on its own.

Before using this toy for the first time, it should be checked for flaws. Occasionally, a glass toy will have a rough spot or imperfection that could snag on skin or tissue. If you find one, you'll want to return it by submitting a support ticket.

I was very happy with this design. As each bump went in, I could feel a satisfying pop. Since they are close together, it was easy to slide in and out, which added a good bumpy sensation to the fullness that glass offers. I was ready for the whole length right away, but anyone not used to glass or just starting with anal toys can build up to taking the entire length, which may make this a good choice for beginners.
This is great as a probe, but the handle is big enough that it can't be worn around for everyday activities. It sticks out way too much to sit down on!
The measurements are:
Total length: 6.5"
Insertable length: 4.5"
Handle: 2"
5 bumps: 4" circumfrence
Other reviewers have mentioned that the bumps gradually increase in size, but mine were all the same size around.

After using my silicone fun factory plug for a while, I was ready for something bigger. I picked this out after reading other reviews and was glad I did! Although I can't wear it around like I can with a plug, its given me plenty of enjoyment during solo play and with my partner. Solo, I like to get it in and then use a dildo or a dildo AND a vibe on my clit. If I'm going all-out with three toys at once, this probe works well because I can get it in and it stays put while I use my hands for the other two. The combination is a favorite of mine when I'm on my own. With my partner, it's a good warm-up for anal sex. Letting him handle it and watch my reaction, really heightens the anticipation.

Glass is one of the safest materials there is and it's easy to clean and sanitize. It can be washed with antibacterial soap, boiled, or put in the dishwasher. I usually wash toys by hand first, being sure to clean in between the textured parts, and then run them through the dishwasher for extra safety.
Lube should always be used with anal toys. Any lube is safe to use with glass. I prefer water-based personally, but silicone is okay too, if you like it.

This toy comes with its own pouch, so I keep it in that for storage. So far I haven't had any trouble, but since the pouch that it comes in isn't padded, I wrap it in clothing for extra padding if I'm traveling with it.

This probe came inside its red velvet drawstring pouch, wrapped up in bubble wrap and paper. I kept the pouch for storage. No instructions are included, so it's a pretty bare-bones approach.
