It's one of those tiny little things that can make a HUGE difference. Battery boxes can be bulky in the pocket or purse, and we all know carrying batteries without the protection of a case can be very dangerous. Keys, pocket change and other metal items can shift, and the next thing you know you have a battery going thermal in your pocket.
Well, here's a brilliant and CHEAP solution. Available separately for $1.13 or in a 4-pack for $2.67 (thats only 68¢ each!), these silicone sleeves stretch so you can slip in a single 18650 battery in a very compact, convenient and most importantly SAFE way to carry with you. If you use 18650s you need these.
