These little milk cartons by Neumeister are both retro and modern. I seem to remember orange popsicles packaged like this from my childhood in England, and this is one of the reasons that I’m attracted to them.
Neumeister says that they created these little packages to be in line with the Arla brand and extend their product range. Each pack is a flavored coffee milk product, so I assume these would take the place of individual creamers in places like hotels/restaurants.
Thanks to my ever-on-the-look-out ex-student, Aditi for the tip!
