Here’s a trick I’ve used for other air tight storage situations. A lot of different types of jars look good for bulk storage. But before you find yourself with a jar of dust in a month or so, perform this simple test on a new jar. After the final wash run some hot water in the jar until it heats up. Dry it and cap it still warm. Set it aside until completely cool, slowly open the lid holding it up next to your ear, listen for the Psssst of in rushing air, telling you it held a good vacuum.
It´s a common procedure for the canning of homemade marmalade (you put uncapped pot with the marmalade in boiling water for a while, take it out and then you put the cap on while it´s still hot), don´t know if the same can be done for snuff or if this will ruin it… Anyway, good test 3_D!.
I hope the jars I got in the mail today hold a tight seal. I bought 3 cases of the cobalt blue jars that someone else posted the link to in another thread. That should be enough to hold me over a while. I got 2 different types of caps to try out so I’ll see if one seals better than the other.
I think the best choice in jars is that…
I’m sure those are great, but much more costly than the ones I just got. I’m no millionaire. 
the specific is 250ml and the price is 1,88euro -> 2.43$
50ml -> 2.31$ in the other hand you have a massive airtight best of the best jar 250ml -> 2.43$
It´s best if the snuff is stored with as little oxigen as possible inside the container apart of it being airtight. If you store a small quantity inside a big container it will degrade faster than in a adequate size container. Get the right tool for each job, just my 2 cents.
always will stay little oxygen at least in the glass jars, i suppose that 250ml and over is for bulk use
Actually oxygen will not always STAY in a well sealed jar that has snuff in it. Oxygen will get used up by the microbial activity of some snuffs. This is why letting snuff “breathe” after opening and taking some out of such storage is helpful.
Why don’t you just half fill the jar with water and give a good shake? No water out, no air in.
I prefer my snuff shaken, not stirred anyway.
Just use your snuff faster and you wont have to worry about storage 
You could also fill the sink up with water and then hold your jar underwater. If you see air bubbles or when you take the jar out if there is water in the jar then you know it has leaks
@snuffmaestro but there’s a huge difference between being airtight and watertight. Air will get through gaps MUCH smaller than water can, so that’s not the best of tests. At least you’re thinking though.
I always exhale hot breath into my jars prier to tighten the lids. gets rid of the oxygen and adds a slight amount of moisture. Works for me.
To re-post… Storage-long term. These are some containers I use or have used for longer terms: Kraft soft (spreadable) Limburger cheese jar. Similar to baby food jars. Kerr-Qorpak 2-4 oz wide mouth lab sample bottles. Use these for my daily snuffs. Coated fiber seals. http://www.qorpak.com/bottles-jars/clear-glass-bottles-jars/clear-graduated-medium-round-bottles Heinz glass gravy jars. Very good for long term. I have some 7+ yr old snuff in perfect condition. Just make sure you get them sealed correctly and tight. Should be difficult to remove lid. Tall glass olive jars. Similar to baby food jars. Any mason style jar with good condition lid/ seal (which can be bought new) Nalgene wide mouth heavy walled HDPE lab ware. Very nice as seal is integral with lid and cannot tear or get lost. Will not break! http://www.thermoscientific.com/ecomm/servlet/productsdetail\_11152\_L10676\_87430\_11964160\_-1 F&T tins. Seal with tape for very long terms. Pottery crocks with Grolsch type wire/ rubber ring closure that cheese is sometimes sold in. Looks very classy and innocuous on shelf or table. The cheese is usually quite tasty also! A good container source I came across… http://www.freundcontainer.com/ Just be sure to clean and de-odorize containers well. (use vinegar, baking soda, ground coffee, etc.) Keep sealing surfaces clean of debris (snuff) Less air space = better. Store in cool area (cellar/frig) away from light and snuff can last for many years. You may even find that some improves with age. (Old Paris for one
@basement_shaman that’s a real good idea, that increases the humidity in the jar requiring the snuff to give up less moisture. I’m sure that Oxygen and oxidation have a part in it, I think loss of moisture is the real enemy. @jpsavage I’ve been wondering about the Nalgene bottle I have several from my backpacking days, I know they make smaller sizes not sure where to find them, They’re a great bottle, nearly indestructable, excellent seal.
The bottles that Abraxas snuff comes in look be be airtight as well. I am sure he researched lengthy to find the best bottle available to preserve his fine products. Same goes for Sir Walter Scott. Both fine snuff in great packaging
