These tiny top shells average 1/4". They have been washed, ready for your projects. There are very few flawed ones. However, they are measured, not counted, so one or two may have been overlooked.
Each packet is a 2" x 3" bag. The one I counted had almost 200 shells.
These shells could use a bit of mineral oil to bring out their true colors. All in all, a nice consistent size shell to work with.
