These Hermit Crabs are a great decorative piece. They are hand blown with a natural shell. The little guy is yellow and blue, and the yellow is black light reactive. And if you are looking for a special color contact me to discuss what you are looking for. They are approximately 3 x 2 x 1 1/2. All pieces vary because they are hand made, and no one piece is alike. No shipping charges will be added to your order, only taxes if applicable.
