A: It depends what kind of cigarillos. If they are the machine-made type, like Swisher Sweets, Café CrÃ¨me, Panter, or Dannemann’s, no need. Handmade cigarillos like the Padron Corticos, Davidoff Primeros, and La Flor Dominicana Mojitos are made by hand, and should therefore be kept in a humidor.
Of course, it can’t hurt to keep even machine-made cigarillos in a humidor. You can just place the whole tin in there, as-is. That said, if you smoke through a tin relatively quickly, it’s probably not necessary.
Moreover, cigarillos (or café cigars), are made by machine due to the difficulty of rolling such tiny cigars. According to one of my resources, it wasn’t until 2003 that some manufacturers like Padron, Davidoff and La Flor mentioned above, et. al., began making handmade little cigars.
