When not in use, I jar my boxes so the snuff inside doesn’t dry out.
My only experiences with snuff “boxes” are the Wilson’s wooden ones. I bought them more as a souvenir item and find them slightly impractical for toting. They spill via the back side of the slide off lid if overfilled and the only advantage I see is imparting a slight flavor due to the wood composition and decanting of certain blends. Of course, this also applies to the type and amount of snuff placed inside. As I’ve stated elsewhere, I use old Packard’s plastic boxes to port my snuff around. Bullets have a limited use but occassionally come in handy. Toque has the best “tins” so far and seem to seal in the freshness without too much hassle. F&T tubes are great but I’m sure the cost of the contents is represented in the packaging. With some imagination there are many things that can be used as snuff boxes. Consider if you need a tight seal for humidity, easy access, and a secure lid to avoid spillage. Some suggestions include but are not limited to; contact lens cases, Altoids mint boxes, Sucrets cough drops plastic boxes, used tins and containers for old snuff, pill boxes, antique snuff bottles, small lidded jars, perfume sample vials, used plastic dip cans, etc… Again, consider if this is to be something you intend to carry around with you or just have sitting on the desk. Good luck with your experiences and don’t be fooled by marketing ploys. Sometimes the answer is already in your house.
