If you have a tupperdor but live in an apartment with no A/C (like I do) in the summer....
- Buy a Coleman cooler
- Buy some of these and freeze them....
- Put the tupperdor in the cooler with the frozen ice blocks not touching the tupperdor and voila. I now keep the cigars in my tupperdor anywhere between 65-72F.
Once I hit 72F or the ice blocks are totally melted, I swap them out for other frozen ice blocks.
