Oyster Chips 10kg Free Shipping

This product will be shipped without being divided into smaller portions.

This is finely crushed oyster shells.
(Please check image 3 for the fineness.)

In my household, we mainly use this as a filter material for aquariums.
It has been particularly useful for raising medaka recently.

We also crush it finer to mix into insect food and bedding, and use it as a calcium supplement for small animals, reptiles, and birds.

Before using it for aquariums, we recommend washing it once with water.
If you use it without washing, the aquarium water may become cloudy.

Please refrain from price negotiations.

Immediate purchase is very welcome.

Thank you for your understanding and agreement on all of the above points, and please accept the 3N (No complaints, No returns, No cancellations) policy.
