Great price
But I give it a 4 instead of a 5 because while some of the cases I purchased will fit 2 18650's quite well, some of them are almost too tight to close properly. But they do close.
ProsGreat price
ConsSome are a little tight fitting.

Works better for CR123A/RCR123A's
Due to the nature of things Lithium Ion, 18650's tend to vary a bit in length and girth, so sometimes a bit of extra force is required to close this case if one or two 18650's are being stored... this makes for a concern the case will pop open, letting these powerhouse cells free to get into trouble. Double check your case to insure it locks up well. This style closure isn't the type Tenergy employs in its AA and AAA cases, which gives a better sense of secure closure, even making it a bit harder to open. This case closes more securely with the bit thinner CR123A's and RCR123A/16340's. With these the fit is a bit loose, so there's some rattling, but by the same loose fit the cover snaps shut more securely without the resistance of a plump 18650 cell fighting it. I also find that pairing one 18650 with two CR123A's works nicely, but if you pair with two RCR123A/16340's, you may find that due to the variance in length of the RCR123A/16340's maker by maker, two of these placed alongside the 18650 may also interfere with the fit and closing.
ProsHolds 4 CR123A's or 4 RCR123A/16340's nicely, closes reasonably securely with these Can hold 2 18650's or a single 18650 plus two CR123A's alongside Comes in two colors to separate types of cells being stored more easily
ConsMay not close securely with certain 18650's due to diameter - be careful to check and press firmly to close lest these cells roam free in your luggage

Used to use plastic pill bottles for my lithium batteries, but I like these cases a lot better. More compact and the batteries don't rattle around so much here, well worth the price.

A Inexspensive plastic case
This is just a inexpensive plastic case, the case has slots for the batteries 123's to lay vertical or horizontal the 18650's lie vertical. "Rattle and Roll" the batteries fit very loose in the containers/ holders and rattle every time you make a step.
ProsUhh their blue...
ConsThe batteries fit very loose in the container and rattle every time you take a step

I no longer have to stuff batteries in odd pill bottles. These cases fit perfect for 18650 & CR123. I even use one to store 18500s.

CR123 case
Item does what they say. It holds batteries. I don't own any 18650s so I have only used it for CR123. I have no doubt that they would fit.

Handy battery case
I agree with the other reviewers. These cases do their job of keeping your 18650s and CR123s secure and together. However, thicker 18650s will make the case hard to close and even harder to open due to the tight fit. You may need to use more than just a fingernail to open the little tab. If the batteries are on the thin side, and there is no pressure on the lid, the locking tab my not hold very well either. A rubber-band will solve that problem though. All in all, a good product to have for those size batteries. (*Note: This is the same case that comes with the Olight 18650 battery if you chose the box and not the blister pack.)

UltraFire Battery Case for 2 18650's
18650 battery fits snugly into place, and lid snaps shut. Would get another one, also customer service and the time it took to get here was very good.

case 18650 / CR123
Not a bad little case, but slighly a pain to open. And i found it can just kinda pop open at times. Solid enough to protect your cells, but if your throwing these in your pack or gear bags ect, I would just throw a quick rubberband around this case just to be one the safe side. With lithium cells , trust me they arnt anything you want loose in a gear bag with any metal objects.Yeah i found out the Scary hard way.
Prossolid enough to protect cells. clear see thru (easy identifiable cells)
Conssometimes hard to open. Sometimes just pops open on its own with the slightest bump. Not really reliable enough to be handled roughly or abused.

Not a tight fit.
The case fits CR123 but they rattle around and do not fit tightly. My Klarus 18650 do not fit because they are slightly oversized so overall I ended up not using these cases.

keeps my extra batteries organized
I bought 2 and use one for 2 18650s and the other for 4 123s. It holds the 18650's snug, no rattle. The 123s are not as snug but so what they stay in the case fine. In either case I did not find any problem with the size of the case. I will be buying more, to carry with me and for the car.
