Optimize your product label so it stands out against competitors wherever it is sold- online or in stores.
Questions you could ask:
"Which label stands out to you most (good or bad) and why?"
"What do you like/dislike about this label?"
"Which label style do you think fits the product the best? Which do you think is the worst and why?"
"Do you prefer (color variation 1) or (color variation 2) for this product and why?"
