Please purchase with the understanding that it is used and the remaining amount is as shown.

This is an environmentally friendly gravel made by melting recycled glass at high temperatures and foaming it into a pumice-like material.
When stepped on, the stones rub against each other and make a surprisingly loud noise, providing easy crime prevention.
Spread it about 4cm thick in areas where you want to prevent intrusion.
It is processed by firing, making it odorless, sterile, and clean.
In addition to crime prevention, laying this gravel in your garden makes it difficult for weed seeds to come into contact with the soil, also providing weed control.
Furthermore, because it contains a lot of air, it has heat retention properties, preventing temperature drops in the soil and preventing cold damage.
It also has water purification properties, so it can be used as a bottom layer for potted plants.

*This product does not contain any herbicides or other chemicals.
*Since recycled glass is used, there may be variations in the color of the gravel. Please understand this in advance.
