The cases are nice, solid and a decent size. They are a bit heavy and appear to be of generally good quality. The only problem I have is that one of them (the white one) has a tiny hole as shown in the picture. There are also cracks on the outside of the shell with holes (also visible in the picture). Update: if using them on hermit crabs please rinse them WELL as there is enough sand in the shells to start a miniature beach. ! This may take a few times, and be sure to rinse out the crevices. I had to fill the shells with water and shake them about 6 times to get all the sand out. The good thing is as soon as I put them in the terrarium both of my germs were on the shells looking at them. They are very picky and have both found a projectile from the order that suits them.
