It depends on how you classify them, but they say there are about a thousand kinds of shells you can find in the seas around Japan.

Without even thinking about things like shells you pick up on sandy beaches, shells you catch along the shore, or what you’d use them for, you end up collecting them just because they’re there, right? So how about making a clock using those shells? You can buy the main clock unit at a 100-yen shop, then place shells for each hour—hamaguri for 1 o’clock, trigai for 2 o’clock, yakōgai for 3 o’clock, and so on.

If you dry the shells and finish them with varnish, they’ll look beautiful!

Dinosaurs are always popular, and many children are sure to love them.

You can create one large dinosaur, or make several different kinds and line them up for a spectacular display! For a diorama-like effect, spread sand over a board, fix it with wood glue or similar, and arrange your dinosaurs on top to create a realistic scene.

Any leftover shells can be used as decorative rocks or stones.
