Lunamax Titanium Doobie Tube, Waterproof, Airtight, Smell Odor Proof, Indestructible Keychain Storage Container Case for Large Joints or Pre-Rolled Cigarettes

Very nicely built for the price, but the photos online don't show the LUNAMX logo that's printed on the side of the actual product. I purchased both this and the same company's "XL" version. Of the two, this is the better machined/finished, although I opted for the larger one. Have yet to test to verify that it is indeed titanium. Metal has faintest taste, but not like aluminum, and similar to that of my Vargo titanium water bottle.If you're looking for a tube to hold the dynavap vaporizer, get the XL tube.

...I flame treated mine and it's beautiful...Very awesome idea if that is your type of thing. Personally I choose titanium because it is hypoallergenic for anything I'm going to be inhaling. It also is not prone to picking up smells or stains.The build is extremely sturdy and this is pretty decent titanium from the looks of it.They included an extra ring too. I ride this thing in a bike bag with tubes/tools/beers and it's great for me.The only thing I can be a crybaby about is the ID (INNER diameter)...it's approximately the size of a AAA battery so whatever you roll needs to be slimmer ish for king size papers. Blunts won't fit.Again for a tough carry it's awesome.

Received a used tube that was described as new, the review of the tube itself is down at the bottom. How do I know this? Because the previous owner used it for what was alluded to in the description, the smell was obvious the second I unscrewed the cap and then verified when I saw ashes down at the bottom. Also noticed some small dings on the base where it must have been dropped on concrete or something. Look, I get it, these are expected to be used for certain herbs and I have no problem with that, but they're also expected to be new when you receive them. I had a different use planned for this tube, and the fact that there's crap in it excludes it from that use. Can't get a replacement because they're currently unavailable, apparently I bought the only one. Now I've found myself in a real dilemma. Do I keep the tube and find some other limited use for it, or send it back knowing that there's potentially enough illicit material inside to get me in legal trouble through the post office...All of that notwithstanding, for the tube itself, I have no real complaints and it'd probably get a solid four star rating. Contrary to other reviews, it is in fact titanium, it's a thick walled tube made from a solid billet which gives it considerable weight at 60g/2.1oz. Threads are well machined and has a good fitting o-ring in the thread relief. Cap is milled from a solid section of billet as well. The bottom is not integral to the rest of the tube, it's either an interference press fit or it's threaded on with some kind of thread locker or sealant, as it doesn't budge (hopefully it's at least sealed for legitimate waterproofing, I don't have any way to test it though). Lathe work is adequate, they didn't use a finish pass so the surface has that vinyl record feel to it, the cap is a few thou oversized from the tube OD, and the decorative cuts are somewhat inaccurate in actual depth of cut. This isn't a typical thin walled formed or spun titanium container that was finished on a lathe, it started out as a solid billet and was machined to spec. The machining inaccuracies are strictly aesthetic and do not negatively affect the tube, one could finish it with sandpaper if a smooth finish is desired.

If it's titanium, it's the heaviest titanium I have ever seen. It's not magnetic, but definitely not aluminum or 304 stainless. It probably really is virtually indestructible. It works well and will fit a cigarette or large herbal rolled equivalent. No complaints, but for the new weight of my key-chain.

Other than the headline, this is precisely what I expected: A sturdy tube, with o-rings to keep water out, suitable for storing a single backup vape battery - or possibly a vape cartridge. The included keyring just barely fits into the drilled-out hole, making the swing a little stiff, but if you lace it into another split-ring there's plenty of play.

The small version, there are two, is about just large enough to fit a cigarette. The larger version is about the same size as the cigar, but not enough to fit that cigar. To the cap, the larger it fits almost 20ml. The smaller fits significantly less than half this volume.

not good for king palm minis sorta sharp edges becareful other than tht its not bad could be cheaper though.

This is a very nice air tight titanium container. The contents stayed bone dry at 30 feet for appx 20 minutes. That was how long I tested it. Probably could have gone deeper and longer. Very well machined and lid fits well. This little thing is a little pricey but well worth it. It really comes down to how much you value what you are keeping in it. Highly recommend.
