Nitecore NBM40.
A great solution to carry x4 18650 lithium batteries for safe transport when traveling made from the very odd sounding vapour -phase gum which is environmentally friendly and very resistant to tearing and has a high level of impact resistance .
Apparently these can also be used to safely carry vape gear when in transit and I noticed it carried a clipper lighter , red Glotoob, my klarus MI1C and a spare CR123 in a county comm delrin case quite well too .
