[solved] What does the number in the diamond mean?

Hello!

I was looking at some items on the Mog Station and wanted to know what something was.

On some items there is a number in a diamond on the item's photo. What does it mean? Does anyone know?

First example:

https://store.finalfantasyxiv.com/ff...n-us/product/1

Second Example:

https://store.finalfantasyxiv.com/ff...n-us/product/2

I thought that perhaps the number meant what level you have to be to use it but the second example is the same item just a bundle of three of the item instead.

Couldn't find the answer myself, so I thought to ask you all.

Thank you in advance!

It's ranked on a Best Seller list, so single Fantasia would be #1 most sold, 3 Fantasia would be #8 on the list etc.

Thank you!!
