10.5mm Round x 5.5mm wide x 3.3 tall or deep. These are solid copper. They are old molds. They are hard to find nowadays, these are more or less a pointed teardrop half. They have a thin lip on the edge. The way we use these is to solder these to your metal to form a flower, or use as leaves or whatever else you can come up with. And I have perfect bumps on it! these on my project and since they are copper, and I can enamel them which is very lovely for many uses. You can solder two of them together for a pointy teardrop shape.
