They appear to be pretty solid but as many others have pointed out the lids don't seal well and don't close properly. Your cupcakes will be exposed and stale. I can only use them as an open container for serving mini cupcakes. I had to cut off part of the "lid" and throw it away. I'm not sure why this design has a bug, but I hope they figure it out.
