So the picture in the advertisements shows a full blast huge flame torch blowing on these!! Well they can handle a little dab of torch heat here and there but let it set just a bit too long and your getting cracks and more. They seem to shatter easy too like into a billion pieces that fly from one side of the room to the next!!! Or when cleaning the whole top will come off with the screen!! LolAnyway it's still a great cute set of straight glass things that are even more awesome that it comes with all the neat colors and the price is unbeatable!!!

These were great at first, but most ended up cracking when exposed to a lower temperature than what they were rated for. I threw out the broken ones, so I can’t get a refund or replacement. Disappointed.

The size is a little big. Besides that, they are high quality and very durable. Price was great too.

These are really high quality glass, nice and thick and assortment of colors. They work really well and I don't know what else to say about them except 5 Stars.
