The link below offers genuine wooden tabatière with the clover leaf zinc and nickel maillechort decoration made by the St. Claude snuffbox industry in the Jura region. The usual dimension is 85x45x20 but I have both larger and smaller examples. The best ones like those illustrated have metal ends. They are made with tight-grained wood such as ebony, rosewood or burl. Unfortunately I dropped my large ebony box down a stairwell in Marrakesh some years back and it didn’t survive bouncing down the steep steps.
I can’t vouch whether these do, but in France they all came with instructions inside the box.as care has to be taken in opening them. Slide your fingers under the lid applying equal pressure along the length. The hinge will then remain undamaged and the box should last a lifetime. Never attempt to open a hinged box using your thumb. Earlier examples are often made with several woods and have larger, more detailed maillechort as well as metal ends.

Years ago I recommended on this forum that one should never discard the F&T tall tins, especially the large size. They are the same dimensions as the 1lb and 2lb tin canisters once found in tobacconists from which you could buy loose and are shaped like that for good reason.
I buy snuff in 1.1lb canisters and when contents become low I transfer everything into F&T tins to minimize the surface area exposed to air.
Provided the tins are well-packed and kept cool (not refrigerated) they keep snuff in good repair.
