A disposable sex toy? Yes, that is what the US Tenga and all the Tengas for that matter are supposed to be. This Tenga is designed for larger men in the US market. I guess we are larger over here than they are in Japan.
All you have to do is open the toy with a little tab on the bottom, take off the bottom cap, and remove the little vacuum sealing tab on the top. The toy is pre-lubed, so I slid right in. It was a little cold at first, but the design felt amazing. After a few minutes, the toy warmed up, and the coldness was gone. I experimented with covering the vacuum hole up top, and the toy felt even better than before. The vacuum it creates feels more like oral sex than any masturbator I have ever tried. I was able to orgasm very quickly, and when I did, it felt like actually cumming inside a woman. After I was done, I pulled myself out of the Tenga, and my penis came out clean, and nothing leaked out of the toy at all!

I thought to myself that I got to use this thing again, so I washed it out as best as I could and left the toy open so it could dry. I used it a couple of days later, and I added some of my own lube, and it felt great again. However, it did feel a little spongier and a little looser. I finished and washed it again, but when I went to use it a third time, it smelt funky. That is the problem. It really is a one-use toy. You really can't clean it out well enough, and it doesn't dry out inside, so bacteria probably grow like crazy inside.

Hard to do a follow-up review on what is a disposable item. I did get three uses out of it and I gave it an "I still like it" rating because I would order one again in the future.
