Miniature solid fuel heating tablets type D91 & type D92
Hello!, I want to know where I can buy these 2 items at?!, I'll describe them to you, their miniature about the size & color of a silver hex nut, but they don't have a hole in them, & I peel the back off of them as I would A postage stamp, these 2 items have a round self adhesive back so I can stick them to a surface, & then I light them up with my cigarette lighter, & then they go off as a whitish flare for about 50 seconds, & then they die down & go out about a couple seconds later. If you can help me out with where I can buy these 2 items, I'd appreciate that any hints & clues will do too?!. Thank-you!
