How many pouches are in a velo?

Could you please clarify for me what exactly a "velo" is, and what purpose pouches in it might serve? It's not a term I'm familiar with in the context of cryptocurrency or finance. Is this a specific product or terminology used in a different industry or region? Without more context, it's difficult for me to provide an accurate answer to your question about how many pouches are in a "velo." Perhaps you could elaborate on the nature of this item or provide some additional information that would help me understand your query better.
