These are 3D printed. They are sturdy and have a foam insert to keep the batteries from moving.
I was surprised to see that these battery cases are 3D printed. They have a foam cushion in the top that keeps the battery from moving inside of the case. All of my 21700 batteries fit, even ones with built-in USB-C charging that are a few mm longer than a standard 21700. They are rather expensive, but they are shipped from a third-party seller, so the shipping is included in the price. I would prefer if the shipping were added separately if ordering several cases. It is a good product and is exactly what I was looking for, which is a 21700 battery case that holds one battery.

Bit pricey but a better option than most other generic cases.
First off it's made in Canada, Nice! The material is a soft plastic but not flimsy or creaky, theres a foam inside to cushion the battery. Why I purchased it, I needed a case to hold the batteries individually and these are big enough to fit the slightly larger 21700 battery with USB-C charging, an example the Nitecore NL2150RX.

Perfect for my 21700s
Perfect, better than expected. They have little bit of foam in the lid which is not shown in the pictures but I really appreciate.

Bought these for my Fenix 21700 batteries. Fit perfectly. Great way to store your batteries or keep them safe whilst travelling. Very well made. Now I’m going to buy them for all my other Fenix battery types. Thank you for making these!! :)
