What is this type of gravel?

[stillife]

Hi Folks,

May I know what type of gravel is this? (grey in colour)

It's an inert gravel?

Where can I get it and how much does it cost?

Thanks!

Isn't the blog URL on the picture itself? Go read the blog, and you will find what gravel it is, right?

Hi Hi Quixotic,

Cos it doesn't look like Magic or the Gex Japanese soil as describe in the blog. It look greyish rather than brown....that's why I ask what kind of soil. Pardon me...

How much is a pack (say 1 kg)? Does it sold in loose form?

Any?
