 Whilst snuff does not enjoy the popularity it once did, it is gradually re-gaining popularity due to the demonisation of smoking and snuff boxes are still made in surprising numbers.Since prolonged exposure to air causes snuff to dry out and lose its quality, pocket snuff boxes are designed to be nearly airtight containers with strong hinges, generally with enough space for only a days' worth of snuff .Snuff boxes are made in two sizes, ones for the pocket and communal boxes made for table use.
