The current description used for differentiating these two generic bandanas is
very ambiguous with the most obvious difference being the single and double tail
ends which I believe would benefit from being mentioned:-
Therefore can I suggest naming them Single and Double Tail End respectively.
I know the single tail end is essentially two tail ends merged together in the
mold design but I don't think this really matters but if this is a problem
you could instead use the term merged tail end and split tail end or something
to that effect?
