They exist.

       For lo these many moons I've bemoaned the fact that there seem to be very few different box sizes.  To a degree it does make sense to have a range from which you can choose the best for the item(s) you are about to ship; see what I mean.  
       However loath though I, usually, am to buy online I was a bit disappointed with the locally bought Laundry Sheets so decided to try A. N. Other brand, only time will tell.
       The title was, nearly, The good, the bad, no ugly.  
The GOOD? The packing box is obviously designed for that precise item.
The BAD?  I looked up the firm & found an address in London and a letter online by the couple who were "Founders" (Which I now can't find), with very Occidental names and a Product called "Freddie" despite a some what Oriental sounding firm name (Yanwen).  
"Yanwen is one of the China's leading 3PL serving Cross-Border E-commerce sellers."
I knew from tracking it that it came from abroad.
       I suspect most of us may have seen items "Designed in the UK", "designed in USA" etc. to avoid the, almost inevitable "Made in China".  It would appear "The Land of Oz" is no better; these were "Manufactured for Etch Digital Pty Ltd. ˜ ˜ ˜ ˜ ˜ ˜ Australia. and "Made in PRC" What isn't these days?  At least we know PRC,  there are those who wouldn't know CCCP was USSR in Cyrillic script.
