    Best for unprotected cells

    Longer cells will fit but the cap won't seat fully into the base.

    They work

    The clear part is two pieces. You put your batteries in and the gray part holds them together. They hold Samsung 21700 batteries no problem. I have other 21700 batteries that won't fit though.

    Looks like it will last much longer than the freebie clamshell cases. This is my 2nd purchase of this case.

    Good stuff.

    Looks like it will have more longevity than the standard clamshell cases. Each side opens independently. Buy with confidence.

    flimsy but better than plastic hinged case

    Posted by Unknown on Oct 25, 2018

    I like the design and holds batteries well. I think these will hold up better than the hinged battery cases where the hinge always breaks. Would have been 5 stars if it was a little more sturdy or silicone.
