Subject, Miniature solid fuel heating tablets type D91 & type D92 Hello I want to know where I can buy these 2 items?, & what company manufacturers them?. 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 items have a round self adhesive back so I can stick them to A surface, & then I light them up with my lighter, & then they go off as A whitish flare for about 50 seconds, & then they die down & go out a couple seconds later. I forget what store I bought these 2 items at, but I do remember the two types of these items that I'm looking for, their called type D91 & type D92 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
