Wow look at all that room for label graphics (duh!) When these are adopted Commercially, make sure you get the credit Brofessor 
…awesome brainworking
Also strikes me it would overall improve shipping, either as a single mailorder by Customers or from the Vendor as a case in a box.
problem with them is lable machines dont put the lables on them so would need a special labeler for them.
Oh?
It’s 2019~!!!
Yer they are out there but if you were getting your juice made through a white lable service they would have to buy that labler and set it up for the square bottles and there probably going to be to much of a tight ass to do it lol but i still think this is the future of eliquide bottles.
