Since the usual egg packaging is translucent plastic --- the clean, transparent egg box sent neuro signals of "premiumness" and "quality" to my brain. Maybe because it looks a bit like the Bountry Fresh egg packaging (photo stolen from welovejenni.blogspot.com).
This marks a new trend in the Philippines (this has been happening for a while in NA, Australia and Europe): private label brands are aiming to be perceived much more than a cheap alternative. Supermarkets are starting to see a big opportunity in repackaging and retailing. The own brand labels just need premium space within the category, riding on the halo effect of the supermarket branding.
