The Treeze Bubble Large is a medium size (1-1/2” diameter) wooden butt plug. The Treeze series of toys are made from laminated wood, a material made in a similar manner as plywood. There's no way that this can be mistaken for the plugged and sanded wood you've seen in construction, though – this is a quality product, and the use of laminated wood brings it several benefits.

The most obvious benefit is the striking color combination. Mine has alternating red, black and tan bands that show off the contours of the plug exceptionally well. Viewed from the side, the plug looks almost like the design on a butterfly's wing, complete with eye spots (perhaps so this toy can look into the core of your being?) All jokes aside it's a neat color scheme that grows on you.

There are more benefits to the laminated wood construction than the color, though. In the Treeze toys the urethane is more than a finish, it completely permeates the wood (Don Wands calls it a hybrid urethane-wood material). This completely seals and waterproofs the toy, so you don't have to worry about chips, dings, or splinters on your Treeze, and apart from avoiding extended exposure to intense sunlight and strong chemicals the finish is quite durable and carefree. It is compatible with all silicone, oil and water-based lubes. The polyurethane is inert as well, so you don't have to worry about chemicals leaching into your system.

The long taper of the Large Bubble makes insertion of this 4-3/4” circumference plug easy, and the 3/4” long neck (1” in diameter) allows this plug to stay in place pretty well after insertion. The base, 1-5/8” in diameter, is not much bigger than the body of the plug, but the flare is abrupt enough that full insertion is highly unlikely unless you're being very rough. While the top edge of the base is slightly curved, the base is hard and irritation is possible during long term wear if you're not careful. I found that intentionally spreading my cheeks when I sat down was generally sufficient to ensure comfort.

The two bumps on the Treeze Large Bubble make this a fun toy for thrusting play, but I didn't notice much natural wiggle while it was inserted. While experimenting I did find that PC contractions (Kegels) gave a very pleasant sensation as the Large Bubble massaged my insides and prostate. Since the Large Bubble is made of a hard material it readily transmits stimuli, to the point where I was able to feel some slight vibrations caused by the skin and hair on my buttocks rubbing up against the base. Naturally that was very faint, but the Treeze toys can be paired with a separate vibrator for some added excitement.

The base is very discreet, so you could probably wear the Treeze out in public without worrying about it being visible. It stays in well enough that I wouldn't be concerned about it popping out in most situations, but its always a good idea to try long-term wear out in private before taking a toy out on the town.

In order to keep your Large Bubble nice, it's best to take some care in the cleaning. Treeze products are nonporous, so they don't need to be covered, but it's best to use a condom if you're planning on sharing. It can be cleaned with soap and water or rubbing alcohol, but bleach and very hot water can abrade the finish so it's best to avoid boiling, dishwashers, and bleach solutions, instead using a condom for sharing.
