Slimline 21700 Battery Case, soft durable material - Pack of 2 (Holds 2 Batteries)

These battery cases seem to be of good quality. The 21700 batteries fit in them perfectly and the lid stays on tight.

Great storage very durable and easy to use very functional and great fit for my rechargeable batteries and durable.

Well made containers. The lids fit so well together that you can't hardly see where the lid meets the container at. The material seems to be durable, however I haven't field tested these yet, but I don't see anything to be worried over.

somebody had mentioned that they were 3-D printed really doesn’t matter how they’re made they’re awesome. They snap together on and off very easily and protect my batteries. I would not worry about dropping these at any distance. I have two sets that hold four batteries and if I buy more batteries, I will definitely order more

These work great for battery storage. Very sturdy but are very expensive. I guess you get what you pay for. The fit is better than any other case I've tried. If the price wasn't so high I'd give it 5 stars but....

I didn't realize when purchasing that these were 3d printed. I avoid anything 3d printed because the quality usually is lacking. Even my friends who 3d print parts, I don't like using. If the part is carrying a load of any sort...avoid 3d printed parts.Anyway, the material used for these battery holders is super flexible and actually feels high quality. I ordered two of these double containers and have one in a rifle bag and one in my spotting scope bag. Very happy with them.

Really safe compartment. Top snaps into place, yet not to hard to open

These are overpriced, but very nice battery cases that should last a long time. The plastic hinges on the cheap battery cases that come with new batteries always end up failing over time.
