IF aged properly. IF they have been left untouched, stored in optimal conditions and they happen to be quality sticks, then they have a chance of aging in this manner. SLB and SBN, and tubos, are superior to dress boxes for aging purposes. Holds the flavor in. Some people then counter, well what about the humidity then. That's a different animal altogether. IF they are stored properly, the humidity for the cigars will be fine in SLB etc. When you "break" a box, even a SLB, and remove some of the cigars, the air will circulate more and diminish the aging capabilities. If you are going for VERY long term, buy quality sticks, avoid dress boxes, and do not disturb.
