When my daughter showed me his clubs, I was skeptical ("in my time" we went in), but not only have I found the practical system but I've bought "a stack" that I chose with spout. Compared to the version where one must unscrew each box when used (and aseptic handling) to reset the funnel-shaped lid, I found this version with spout on each floor, much more convenient! Hint: spay your boxes, whatever their system with a cold sterilization tray which damages less plastic than heat sterilization.
