Those are pretty sweet. Would be great to have a couple extra batteries clipped to a belt loop. I am in the process of making some from PCV piping and caps. Not as elegant as those but a little bit cheaper and easier than trying to buy those from Germany eBay.
I bought at least 2 in each size at BIC. We know the large fits the 18650 cells. I will find out if the others fit the smaller cells when I get them. Judging from the exterior dimensions I think they should.
Also, the small plastic pocket size bottle that Tylenol comes in is good for one AA size cell. I usually see them around the checkout stands in stores.
I got mine from buyincoins. I requested and received silver for smaller containers and silver/black for large. Large is good for 18650, smaller sizes weren't good for any batteries I have (smallest is too skinny for AAA, medium is too short).
Sorry, guys…I forgot about this thread. What he said ^
The large is great and I highly recommend them but you may or may not be able to fit protected cells in them due to inside machining tolerances. All 3 of the large I ordered fit unprotected Panasonics easily. One fits with no rattle (end-to-end), another fits with some rattle, and the third has lots of rattle. That third one has enough rattle to where I can fit a protected TF Flame but the other two cannot.
The medium is too narrow inside where a 16340 will just not fit. It might have lengthwise but too narrow widthwise. Can't even use them for wooden matches (too short). Good for folded cash stashing for emergencies.
The small are useless. Too narrow and short for even a 10440. Too narrow, in fact, for many pills. Great for folded notes or info and for use as zipper fobs on your kid's jacket or on their backpack.
