Mister B Steel Thurster Ball Stick is not only great for playing the prostate, the smooth balls feels great as they move in and out of your hole. The handle makes it easy to control and you can easily get a good grip on it especially if you use it on others.
You can use approx. 14cm of this toy and the diameter varies from about 12mm to 20mm.
With the Mister B steel toys, you get the opportunity to play with temperatures as steel is fantastic both to cool down but also to warm up (beware of extremes as the skin is also affected by the temperature). Steel does not absorb lubricant, so you have to use significantly less than you are used with other toys, just as it is super easy to clean after use.
