Upon first seeing the name 'Mignon Sweets,' the only thought that ran through my head was 'what a bloody pretentious name!' Upon having done a bit of research, Panter is a very well-selling brand, so they must be doing something right... but onto the cigarillo itself.
The Mignon Sweets were most certainly sweet, a little too sweet for my taste, but I can appreciate that some people enjoy that, and certainly many non-smokers prefer to sit in clouds of sweet smoke rather than non-sweet smoke... I also found them to have an incredibly nutty flavour (macadamia nut perhaps?), more so than any other tobacco I have tried. The cigarillos were made of a hybrid filler and were moderately tarry. Unfortunately they also succumbed to the bane of most cigarillos- becoming unbearably hot towards the end.
The Panter 'Mignon Sweets' (as well as most of the rest of their cigarillo line) will cost about £8.50 for twenty, so not a bad price. They can also often be found in Duty Free at airports for considerably less (my associate found them for €4.40 for 20 in Amsterdam).
