Review on Premium Stansport Wood Charcoal Solid Fuel Sticks - Convenient 12 Pack by Dmitriy Kingsley

I've had this style of hand warmer for over twenty years. but not used for a long time. I bought 2 packs of these sticks and a used hand warmer for my trip up north. The first thing that struck me was that these sticks are significantly darker than the ones I've used, which were more of a silvery color. When you try to light these chopsticks they sometimes flare up and throw small sparks, one of which burned a hole in my bottom glove. I heated the end with a lighter and blew on it until about 1/2 inch was glowing orange on all sides. I put it in a heating pad and after 10 minutes it was cold. I restarted it again and got the same result. I tried a second pack and a new heating pad and got the same results. When I got back from my trip I tried to light it up with a mini flashlight and managed to get it to glow and work properly.
