The Kama Diva Bubble Plug by Don Wands is the first non-flexible plug I’ve used. It also happens to be the first Urethane plug I’ve ever owned. It's a very attractive looking toy that has multiple colors swirled together.

Urethane, from what I’ve found in my research, is phthalates free, waterproof, hypoallergenic, and can be used with both water and silicone based lubricants. The plug that I have has very small pores in a few locations, so covering it with a condom would be best if used for sharing. While I have no experience with glass plugs|Glass buttplug, this toy does feel lighter than glass toys of similar size.

The Bubble plug is definitely not for beginners. It has a 5” circumference and an insertable length of 4 ¼”. I made sure to have plenty of lube on hand when I used this. The tapered head makes insertion easy as you feel yourself stretching to accommodate the girth. The bubble feels absolutely amazing going in, but because the neck is so short and the base is so large that you can’t press it firmly against your anus, the bubble tends to pop out. This provides a nice sensation, but does get a little annoying when you just want it to stay in place. I’ve had no problems with the plug entirely popping out because of the indent above the bubble.

While the Plug arrived in a very large hard plastic container, there was also a pouch to store the plug in. This has so much padding it could double as a pillow if it were a little larger! It provides a great amount of protection for storing the plug.

The Kama Diva Bubble plug was a great introduction to hard anal plugs. The bubble felt amazing and the plug stayed in well, I only wish the round base was either a little smaller or more anatomically correct. For those worried about the possibility of having an anal toy slip in too far, this would be a good choice as the base is huge.
