Turban Shells, Shells, 15 pieces, approximately 6-7cm in size.

Turban Shells (Sazae) - Shells

Sazae from Ishikawa Prefecture, tumbled by rough waves.

15+ pieces
We will add one piece if it fits in the end.

There are cracks and chips.
Please see the photos.

How about using them for filter media or a biotope? (Effective for water purification and preventing water acidification.)
Also ideal for saltwater fish.

Simply submerging them directly in your aquarium is also effective.

They have been bleached, boiled, washed, and sun-dried.
The color may have slightly changed from the photos due to sun-drying.

Personally, I don't think there is any odor.

Thank you for your understanding before purchasing.
