The Negra are maduro, the Dulce are shade grown wrappers, Red Eye are triple ligero, Cafecitas are cigarillos and come in a tin, and the Cafe Con Leche has a combined maduro and shade wrapper.
I also keep my infused sticks separate from the non-infused. The scent will transfer, and if all you are getting is the Tabak Especial, keeping them all together will help keep the scent and flavor from diffusing so much. (In my experience.)
