Pumice Stone, Approx. 474g, Approx. 1-3cm, Beige

Purchased at a home improvement store several years ago. I don't remember the manufacturer or the exact product name.

*I bought this to raise the substrate level in my goldfish tank, but I ended up not using it and kept it stored in a storage bag.
During storage, the storage bag tore, and green, brown, and white plastic mixed in. I removed as much as I could, but some may remain, which is why I've listed it as scratched and dirty. Please judge the condition from the photos.

[Size] Approximately 1-3 cm
*Please be aware of the size if it is a concern.

[Weight] Approximately 474g
*Photo 2 shows the weight excluding the transparent tray (approx. 152g) and including the bag (approx. 5g). Please understand.

[Packaging and Shipping Method]
Will be shipped in a double-layered OPP bag, inside a non-transparent, Yu-Packet Post compatible plastic bag.
*There is a possibility of cracks or breakage during shipping. Thank you for your understanding.

? Please wash before use.
? I have 474g of pumice stone available here, and two other items currently listed (approx. 774g). I believe this is a good deal for those who want a small amount, so please consider it.^^
