## Description

A sleek, protective and durable case for 21700 Batteries. The case is made out of a soft but very durable material that can withstand impacts, to protect your batteries. Package includes 2 full battery cases; each battery case can hold 2 x 21700 Batteries, (batteries not included). Design fits both protected and unprotected batteries (up to 78mm in length).

Review: 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.
Review: Great value - Very high quality. Fits like a glove.
