What physical observation of a dry pyramid bag suggests the shape might offer little functional advantage?

Answer

If the bag is packed tightly to the seams before water is added

Consumers can attempt to gauge the sincerity of a brand's commitment to functional design by examining the dry pyramid bag. If the bag appears already packed tightly to its seams with tea leaves before any water has been introduced, it signifies that there is minimal empty space remaining above the contents. When this happens, the leaves lack the necessary room to circulate and expand freely, meaning the shape provides very little functional benefit over a flatter design, as the primary mechanism of superior infusion is compromised from the start.
