I've been using and recommending those for 10 years, but when I do I tell people, please, do not google their original name at work. The original name was "fatty striper" NSFW LOL.

I have swapped tubeless tires with these, without breaking the seal, but its a bit hard to do - specifically its hard to keep the valve in the liner when doing this. Its basically the thickness of a latex balloon. Works well in helping a troubled tire seat on a rim, preventing burps, and preventing random leakage issues.
