Hello, @Seller_pVgVEVqV3oGO5,

Thank you for your patience and for bringing your question to the forums.

The type of variation available depends on the type of product you are listing. For example, for cookies, you may offer a flavor variation, for a t-shirt you may offer a size and color variation, and so on.

In our forum for US, my peer posted amazing information that will be useful for you:

My best wishes for you and your business,

Sunnie
