The shell for diving is composed of two shell halves and a connecting ring (O-Ring). The shell halves are individually available in different colours and can be individually combined to a shell. That makes it possible to hide an object, such as a "pearl", in the shell. As material we use a soft, certified, food safe and non-slip plastic with a high density. The shell as well as the individual shell halves sink quickly and are easily visible thanks to the striking colours. The shell half is 13cm wide, 10cm long and 2.5cm high and fits in every bath bag. The single shell half is delivered in a nice cardboard box. We wish you a lot of fun with shell diving, be it as a mermaid, at home in the pool, during swimming lessons or on holiday at the beach.
