Perfect size. I wish it were just a little more flexible, but I would buy it again. It is not dishwasher safe.These are so great for making hot cocoa bombs. I cut it into three different molds so that it was easier to use. Once the chocolate hardens it’s just fell right out of the mold. Perfect size.I was expecting something different but it turned out okay. The molds are plastic and I had to cut them for my project. I followed instructions on the package and they seem to work.Made hot cocoa bombs... chocolate released easilyThe picture I ordered from showed silicone. I got these plastic ones that will break in storage or after a few uses.this bomb mold is smaller than I expected, but it does release well. i used these for making bath bomb/fizzies for christmas gifts, and they were easy to work with and use, but each half is only about 4 inches in diameter, which isn't much.overall I would still recommend this product, because it functions properly, but it won't create a giant bath bombAt first I was disappointed because I thought these molds would be easy to use to make bath bombs with. Unfortunately, they aren't. But I figured a way I can use them :o). I made my creations called bom-boms. They are half of a bath bomb. I love it. I can make twelve at a time :o) So happy I figured out a way to keep the molds I purchased instead of sending them back. Thanks J.Bressler!!Like others have posted I too was disappointed when I recieved only one mold. I tried everything to make round bath bombs with this. If you want to make round bath bombs, do not buy this mold. If you are satisfied with half-sized bath bombs, then this is perfect.
