Lt. Description on the box, there is a bag of "robust polyamide fabric", which I can confirm: robust and very solid! One has the impression that one can not better protect the lamp. Back there is a loop, secured with Velcro and additional push button, so you can carry the bag on your belt. Both Velcro fasteners make a solid impression.
How you want in your pocket but still 4 spare batteries accommodate (with lamp ???), she will not reveal to me and is simply nonsense (another reviewer: "room for 4 batteries ..."). Even if you pass pushes the batteries on the lamp housing into the bag and squeezes, this is obviously not practical: the lateral rubber dilate, the lamp housing may scratch - just utter nonsense!
The original quote on the package is also actually "double elastic sidewall accommodate extra batteries." The side walls are actually twice, but are sewn up with a small mini tab to reinzubekommen better the lamp. When filling instead of the lamp the batteries in the bag it comes naturally - but then you could poke small carrots or pens!
But that is also a storage box for the lamp and not on the batteries!
Pocket ground a small hole is (clean sewn edge). This adjusts the strap to the lamp, if you want to let them down rausbaumeln from his pocket.
A really perfect product, which is likely to keep tens of years - smooth 5 star !!!
