I sometimes do not have room for cigar tins I order to fit in my Tupperware humidor . Some tins come with a Boveda pact in them , cigars are wrapped and the tin itself also . These I may leave out till have room to put it in . Question is how long is to long for these to not be put in a humidor ? I order some tins of 10 cigars in 5 tins (Deadwood Sweet Jane) or and by time I get to the last tin and put it in my humidor is 8 -10 weeks maybe . To me I have not noticed anything off of quality from the 1st tin to last tin . Also some cigar tins are ones I don't smoke as much . Now they are in the humidor but do I need to keep the lid cracked to be sure they stay nice or will they be ok with the tin closed ? If anyone is wondering I enjoy smokes that last 15-30 minutes mostly maybe 4x38 but also keep a collection of larger size when I do get in the mood to spend 45-60 minutes relaxing .
