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

Turban Shells (Sazae) - Shells

Sazae from Ishikawa Prefecture, tumbled by rough waves.

15+ pieces
We will include one if it fits in the final packaging.

Cracked and chipped shells are included.
Please refer to the photos.
The 500 yen coin in the photo is not included.

How about using them for filter media or 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 with water, and sun-dried.
The color may have slightly changed from the photos due to sun-drying.

Personally, I don't detect any odor.

Thank you for your understanding before purchasing.
